Introduction

You bite into a Wendy’s Breakfast Baconator and taste something creamy, nutty, and absolutely delicious that you can’t quite identify. It’s not hollandaise sauce. It’s definitely not regular cheese. So what is that mysterious sauce on Wendy’s breakfast sandwiches?

The answer is Wendy’s Swiss cheese sauce—a proprietary, breakfast-exclusive condiment that’s become surprisingly controversial among fast food fans. Some people swear by it, calling it the secret ingredient that makes Wendy’s breakfast special. Others… well, let’s just say they have strong opinions in the opposite direction.

Here’s the important part: This Swiss cheese sauce is NOT the same as Wendy’s dipping sauces like Signature Sauce, Sweet Chili, or Ranch that you get with nuggets and tenders. Those are completely different products. The breakfast sauce is its own unique creation, and it only appears on breakfast menu items.

In this complete guide, we’ll reveal exactly what Wendy’s breakfast sauce is, what it tastes like, which breakfast items feature it, and—most importantly—how to make a perfect copycat version at home. Whether you’re craving it after breakfast hours end at 10:30 AM or you just want to make it yourself, we’ve got you covered with everything you need to know.

We’ve personally tested this sauce, analyzed the ingredients, researched customer reviews across Reddit and TikTok, and perfected a copycat recipe that captures the exact creamy, nutty flavor of the original. Let’s dive in.

What Is Wendy’s Breakfast Sauce?

Wendy’s breakfast sauce is a proprietary Swiss cheese sauce made with Swiss cheese, butter, flour, milk, and secret seasonings including nutmeg and sodium citrate. It’s a creamy, warm cheese sauce served exclusively on Wendy’s breakfast menu items from 6:30 AM to 10:30 AM.

Let’s break this down a bit more, because there’s actually some confusion about this sauce online.

The sauce is officially called “Swiss cheese sauce” in Wendy’s menu descriptions. It’s not just melted Swiss cheese slapped on a sandwich—it’s an actual sauce with multiple ingredients blended together. Wendy’s introduced this sauce when they launched their nationwide breakfast menu in March 2020, making a big comeback to the morning meal market after previous breakfast attempts.

What Makes It Different from Other Wendy’s Sauces

The Swiss cheese sauce is breakfast-exclusive, meaning you can only get it during morning hours. It’s not available all day like the dipping sauces. When 10:30 AM rolls around, breakfast service ends, and so does your chance to get this sauce (until the next morning).

The dipping sauces—Signature Sauce, Sweet Chili, Ranch, Honey BBQ, and Ghost Pepper Ranch—are completely different products. Those are for nuggets, tenders, and fries, and they’re available all day long. It’s a common mix-up, especially when you search online, because Google often shows articles about Wendy’s dipping sauces when you’re actually looking for information about the breakfast sauce.

Here’s a quick comparison so you can see the difference:

Sauce Type	Used For	Availability
Swiss Cheese Sauce	Breakfast sandwiches	6:30-10:30 AM only
Dipping Sauces (Signature, Ranch, BBQ, etc.)	Nuggets, tenders, fries	All day

So why did Wendy’s create this sauce in the first place? Well, they wanted a signature element for their breakfast menu—something that would set them apart from McDonald’s and Burger King. The Swiss cheese sauce adds a creamy, savory element that complements their fresh-cracked eggs and Applewood smoked bacon. Instead of just using a plain slice of cheese, they went with something more special.

💡 Did You Know?
Wendy’s specifically calls it “Swiss cheese sauce” instead of just listing Swiss cheese as a slice because it’s a proprietary recipe, not just melted cheese. The sauce contains special emulsifiers that keep it smooth and creamy, even when it sits under a heat lamp for a few minutes.

Why It’s Called “Swiss Cheese Sauce”

Unlike a simple cheese slice, this sauce is made using a roux-based method (butter and flour cooked together) combined with Swiss cheese and milk to create a pourable, smooth consistency. This cooking technique is similar to making a French Mornay sauce or a classic béchamel sauce with cheese added.

The term “sauce” indicates that it’s been cooked and prepared as a separate component, not just cheese that’s melted onto the sandwich. This is an important distinction because the cooking method affects both texture and flavor.

What Does Wendy’s Breakfast Sauce Taste Like?

Wendy’s Swiss cheese sauce has a creamy, nutty, and mildly tangy flavor with subtle sweetness. The texture is smooth and velvety when served warm, with a buttery richness and delicate notes of nutmeg that complement breakfast sandwiches perfectly.

If you’ve never tried it before, imagine a really good cheese sauce—not the sharp, aggressive flavor of nacho cheese, but something much more refined and breakfast-appropriate. Here’s what you’ll notice when you taste it:

The Flavor Profile Breakdown

The dominant characteristic is creamy and rich. This is the first thing that hits you. It coats your mouth in a pleasant way, similar to hollandaise sauce but with a cheese-forward flavor instead of lemony notes.

You’ll pick up on nutty undertones pretty quickly. This comes from two sources: the Swiss cheese itself (which naturally has a nutty flavor) and a secret ingredient we’ll talk about later—nutmeg. It’s subtle, not overpowering, but it’s definitely there.

There’s a mild tanginess to the sauce, but nothing like sharp cheddar. Swiss cheese has a much gentler tang that balances the richness without making your mouth pucker.

You might detect a hint of subtle sweetness in the background. This isn’t sugary sweet—it’s more like the natural sweetness that dairy products have, which helps balance all the savory elements.

And finally, there’s a buttery quality that makes everything feel indulgent. This comes from actual butter in the recipe, which adds richness and helps create that silky mouthfeel.

The Critical Texture Factor

Here’s the critical part about texture:

When the sauce is served properly at the right temperature (warm), it’s smooth, glossy, and velvety. It pours nicely over your breakfast sandwich without being too runny or too thick. This is how it’s supposed to be.

But—and this is a big but—when the sauce gets cold, things go downhill fast. Cold Swiss cheese sauce becomes lumpy, gelatinous, and honestly kind of gross-looking. The texture completely changes, and the flavor becomes muted. This is actually the source of most negative reviews online.

People on Reddit have complained about getting sandwiches with “weird lumpy Swiss stuff” on them, and in almost every case, the issue traces back to temperature. The sauce just wasn’t served hot enough. We’ll talk more about this common problem in a dedicated section below.

How Does It Compare to Other Breakfast Sauces?

Since a lot of people wonder how this stacks up against other creamy breakfast sauces, here’s a quick rundown:

Vs. Hollandaise Sauce: Swiss cheese sauce is nuttier and less lemony than hollandaise. Hollandaise has that bright, acidic tang from lemon juice, while Wendy’s sauce is more cheese-forward and savory. Both are creamy, but hollandaise is lighter and fluffier because it’s made with egg yolks instead of flour.

Vs. Nacho Cheese: This isn’t even close. Nacho cheese is sharp, aggressive, and very orange. Swiss cheese sauce is much more refined, with a pale yellow color and a gentler, more sophisticated flavor that works better for breakfast.

Vs. White Sausage Gravy: The sauce is thinner than traditional white gravy and has a completely different flavor base. Gravy is peppery and flour-forward, while the cheese sauce is—you guessed it—cheese-forward with nutty notes.

Vs. Melted Swiss Cheese: If you just melted a slice of Swiss cheese on your sandwich, it wouldn’t taste like this. The sauce has additional ingredients that make it more complex—the nutmeg, the butter, and the emulsifiers that create that smooth texture you can’t get from a plain cheese slice.

👨‍🍳 Chef’s Insight:
The subtle nutmeg in Wendy’s Swiss cheese sauce is what sets it apart from ordinary cheese sauces. Nutmeg is a classic pairing with cheese sauces (think mac and cheese or fondue) because it enhances the creamy, dairy flavors without overpowering them. It’s the kind of ingredient that you might not consciously notice, but you’d definitely miss it if it wasn’t there. This technique comes from classical French cooking, where nutmeg is traditionally added to béchamel and Mornay sauces.

What Do Actual Customers Think?

The sauce is pretty polarizing. Scroll through Reddit threads or TikTok videos, and you’ll see people on both extremes. Die-hard fans say things like “the sauce makes the sandwich” and “I could drink this stuff.” One TikTok creator posted a video of themselves making the sauce at home with the caption “The sauce makes it 👌🏼” that got hundreds of thousands of views.

On the flip side, some critics describe it as “too mayo-like” when it’s served cold, or they find it just plain weird on a breakfast sandwich. One Redditor wrote, “Is the ‘Swiss’ on the breakfast sandwiches just a sauce? I had to wipe it off, and it’s still nasty. Can’t even eat this sandwich.”

But here’s the thing: Most negative reviews mention the sauce being cold or having a weird texture. When served at the proper temperature (warm and smooth), even people who were initially skeptical tend to change their minds.

Which Wendy’s Breakfast Items Have the Swiss Cheese Sauce?

Wendy’s Swiss cheese sauce appears on six breakfast items: Breakfast Baconator, Breakfast Burrito, Bacon Egg & Swiss Croissant, Sausage Egg & Swiss Croissant, Bacon Egg & Cheese English Muffin, and Sausage Egg & Cheese English Muffin. All are available from 6:30 AM to 10:30 AM daily.

Not every item on Wendy’s breakfast menu features this sauce. Some sandwiches, like the Honey Butter Chicken Biscuit and the Maple Bacon Chicken Croissant, use different sauces (maple honey butter in those cases). But if you’re specifically after that Swiss cheese goodness, here’s your complete guide to which items have it.

1. Breakfast Baconator ⭐ (Flagship Item)

This is the flagship breakfast sandwich, and it’s where the Swiss cheese sauce really shines.

What’s on it: A brioche bun loaded with a signature square sausage patty, a fresh-cracked egg, six strips of Applewood smoked bacon (yes, six!), two slices of American cheese, and a generous topping of Swiss cheese sauce.

Why it’s popular: The sauce complements both the bacon and sausage perfectly. With all that protein, you need something creamy to tie it together, and the Swiss cheese sauce does exactly that. The nutty flavor pairs especially well with the smoky bacon.

What you should know: This is a serious breakfast sandwich. It’s filling, loaded with bacon, and not for light eaters. The brioche bun is soft and slightly sweet, which balances the savory sauce and meats.

Nutrition note: According to Wendy’s nutrition information, the Breakfast Baconator contains approximately 730 calories. The Swiss cheese sauce contributes to the overall richness and calorie content. (Source: https://www.wendys.com/nutrition)

2. Breakfast Burrito

If you prefer your breakfast wrapped up and portable, this is your move.

What’s in it: A tortilla wrapped around two fresh-cracked eggs, six strips of Applewood smoked bacon, seasoned breakfast potatoes, two slices of American cheese, and—of course—Swiss cheese sauce. It comes with two Cholula Original Hot Sauce packets on the side if you like extra spice.

Why it’s popular: The sauce mixes with the scrambled eggs and potatoes, creating a creamy, cohesive filling. Every bite has a little bit of everything, and the sauce helps prevent it from being dry.

Pro tip: The burrito is great for eating on the go. The sauce stays inside the tortilla wrap, so you don’t have to worry about it dripping all over your car.

3. Bacon, Egg & Swiss Croissant

This one’s for people who love flaky, buttery croissants for breakfast.

What’s on it: A flaky croissant bun with Applewood smoked bacon, a fresh-cracked egg, and Swiss cheese sauce.

Texture note: The sauce soaks into the layers of the croissant, which some people love and others find a bit messy. If you’re a croissant fan, though, this combination of buttery pastry and creamy sauce is pretty amazing.

4. Sausage, Egg & Swiss Croissant

Same concept as the bacon version, but with sausage instead.

What’s on it: Flaky croissant, grilled sausage patty, fresh egg, and Swiss cheese sauce.

The difference: The sausage is heartier and more savory than bacon, so you get a different flavor profile. If you’re a sausage person, this is your jam.

5. Bacon, Egg & Cheese English Muffin

A lighter option that still packs plenty of flavor.

What’s on it: Toasted English muffin, Applewood smoked bacon, fresh-cracked egg, American cheese, and Swiss cheese sauce.

Why choose this: English muffins are less calorie-dense than croissants or brioche buns, so this is a good middle-ground option if you want the sauce without going overboard.

6. Sausage, Egg & Cheese English Muffin

Same as above, but with sausage instead of bacon.

What’s on it: Toasted English muffin, grilled sausage, fresh egg, American cheese, and Swiss cheese sauce.

Who it’s for: If you want a classic sausage, egg, and cheese sandwich with a gourmet twist (the Swiss cheese sauce), this is it.

💡 Ordering Tip:
You can request extra Swiss cheese sauce on any breakfast sandwich at most Wendy’s locations, usually at no additional charge. Some locations might charge a small fee (around 25-50 cents), but it never hurts to ask! Just be polite about it since it’s not an official menu option. According to customer reports on Reddit and social media, most Wendy’s staff are happy to accommodate this request.

What’s in Wendy’s Breakfast Sauce? (Ingredients Breakdown)

Wendy’s Swiss cheese sauce contains Swiss cheese, butter, flour, milk (or cream), salt, pepper, and two secret ingredients: sodium citrate and nutmeg. Sodium citrate creates the smooth texture, while nutmeg adds the signature nutty flavor.

Now we’re getting to the good stuff. Wendy’s doesn’t publish the exact recipe for their Swiss cheese sauce—it’s proprietary, which means they keep it secret to maintain their competitive edge. But based on extensive taste testing by food bloggers, analysis from copycat recipe experts, and observations from Reddit users and TikTok creators, we’ve pieced together what’s actually in this sauce.

Food hacker Todd Wilbur, who runs Top Secret Recipes and has spent over 30 years reverse-engineering restaurant food, created a copycat recipe for the Breakfast Baconator that includes the Swiss cheese sauce. His analysis lines up with what other independent testers have found.

Source: Todd Wilbur’s analysis at https://topsecretrecipes.com (Todd Wilbur is a New York Times bestselling author who has published multiple cookbooks dedicated to recreating restaurant recipes through reverse engineering and testing.)

Let’s break down each ingredient and why it matters:

Core Ingredients

1. Swiss Cheese (The Star Ingredient)

This is obviously the main flavor component. Swiss cheese has a mild, slightly sweet, nutty flavor that’s much gentler than sharp cheddar or aged cheese. It melts relatively smoothly compared to some harder cheeses.

Here’s the key detail: Wendy’s most likely uses Swiss cheese “Singles” or a Swiss cheese product rather than aged Swiss from the deli. Why? Because processed cheese products contain something magical called sodium citrate (more on that in a second), which helps them melt into a perfectly smooth sauce without getting gritty or grainy.

Food Science Fact: According to food science research, Swiss cheese contains natural compounds that give it a nutty, slightly sweet flavor profile. The cheese-making process creates propionic acid, which is responsible for Swiss cheese’s characteristic taste and the formation of its signature holes.

2. Butter

Butter serves two purposes. First, it adds richness and creates that luxurious, creamy mouthfeel. Second, it’s used to make what’s called a “roux” (pronounced “roo”), which is a mixture of butter and flour that thickens the sauce. This is a foundational technique in French cooking used to make béchamel sauce (one of the five French “mother sauces”) and Mornay sauce (béchamel with cheese added).

3. All-Purpose Flour

The flour is the thickening agent. When you cook flour with butter, it creates a roux, which is the foundation of most cream-based sauces. The flour gives the sauce body so it’s not just thin, melted cheese. The roux also helps prevent the cheese from separating or becoming oily when heated.

4. Milk or Heavy Cream

This is the liquid base of the sauce. Milk thins out the cheese so it becomes pourable instead of just a thick glob. Wendy’s likely uses whole milk or a combination of milk and cream to get the right consistency and richness. Whole milk contains about 3.25% fat, which contributes to the creamy texture without making the sauce too heavy.

5. Salt & Black Pepper

Basic seasonings that enhance all the other flavors. Salt is especially important because it makes the cheese taste more “cheesy” and brings out the nutty notes. According to culinary science, salt enhances flavor perception by suppressing bitterness and amplifying savory notes.

Secret Ingredients (The Game-Changers)

6. 🔑 Sodium Citrate ⭐ SECRET INGREDIENT #1

This is the magic ingredient that most people don’t know about, but it makes all the difference.

What it is: Sodium citrate is a salt derived from citric acid. It’s completely safe to eat and is actually used in tons of processed foods. If you’ve ever wondered why Velveeta or American cheese slices melt so smoothly while regular cheese gets grainy, sodium citrate is the answer.

Why it matters: When cheese melts, the proteins can clump together and create a gritty, separated texture. Sodium citrate prevents this by binding to the calcium in the cheese proteins, which stops them from clumping. The result is a perfectly smooth, creamy sauce.

Where to find it: Sodium citrate is found naturally in processed cheese products like Swiss Singles. If you’re making the sauce at home with regular Swiss cheese, you can buy food-grade sodium citrate online from specialty suppliers like Modernist Pantry or Amazon.

The science behind it: Food scientists call sodium citrate an “emulsifying salt” because it helps fat and water stay mixed together instead of separating. According to the food science book “Modernist Cuisine,” sodium citrate works by sequestering calcium ions in cheese, which allows the casein proteins to remain dispersed and prevents them from clumping together during heating.

🧪 Food Science Fact:
Sodium citrate works by binding to calcium in cheese proteins, preventing them from clumping together. This is why processed cheese melts so smoothly—it contains sodium citrate! Research published in food science journals shows that sodium citrate at concentrations of 0.5-3% by weight can transform any hard cheese into a smooth, meltable product. You can buy food-grade sodium citrate online (Modernist Pantry or Amazon) or use processed Swiss Singles as a shortcut, since they already contain it.

7. 🔑 Nutmeg ⭐ SECRET INGREDIENT #2

Here’s where things get interesting. Multiple independent testers—food bloggers, Reddit users, and TikTok creators—have all reported detecting a subtle, warm, nutty spice in Wendy’s Swiss cheese sauce that they identify as nutmeg.

What it is: Nutmeg is a warm spice with a sweet, nutty flavor. It’s the seed of the nutmeg tree (Myristica fragrans) and has been used in cooking for centuries. It’s the same spice used in pumpkin pie, eggnog, and béchamel sauce.

Why it matters: Nutmeg is a classic ingredient in cheese sauces. Professional chefs add it to mac and cheese, cheese fondue, and Mornay sauce (a fancy French cheese sauce) because it enhances the creamy, dairy flavors without overpowering them. It’s one of those ingredients you might not consciously taste, but you’d definitely notice if it was missing.

Historical context: According to culinary history, the pairing of nutmeg with cheese sauces dates back to classical French cooking. Auguste Escoffier, the legendary French chef who codified French cuisine in the early 1900s, included nutmeg in his recipe for Sauce Mornay (cheese sauce) in his influential cookbook “Le Guide Culinaire.”

How much: Just a pinch. Nutmeg is potent, so a little goes a long way. Too much, and your sauce will taste like pumpkin pie. Just enough, and it adds a subtle warmth and depth.

Customer detection: People on social media have specifically mentioned tasting nutmeg in the sauce. Food bloggers who specialize in copycat recipes have also identified nutmeg as a key component through blind taste testing and comparison with traditional cheese sauce recipes.

Important note: Wendy’s has never officially confirmed that nutmeg is in their sauce, since the recipe is proprietary. But based on traditional cheese sauce recipes, professional culinary techniques, and multiple independent taste tests, it’s highly likely that nutmeg is part of the formula.

What the Sauce Doesn’t Contain

It’s also helpful to know what’s NOT in Wendy’s Swiss cheese sauce, especially if you’re comparing it to other breakfast sauces:

❌ No lemon juice (unlike hollandaise sauce, which is lemon-forward)
❌ No egg yolks (unlike hollandaise sauce, which uses egg yolks as the emulsifier)
❌ No vinegar
❌ No artificial cheese flavor (it uses real Swiss cheese)
❌ No hot peppers (it’s not spicy at all)
❌ No mayonnaise (despite some people saying it tastes like mayo when cold)

This makes it a pretty straightforward cheese sauce, just elevated with those two secret ingredients that make all the difference.

This copycat recipe is inspired by professional food hacker Todd Wilbur’s techniques and refined through additional testing to match the exact flavor profile of the original sauce. We’ve made this recipe over a dozen times with different cheese types and ratios to dial in the perfect balance.

🍳 Wendy’s Swiss Cheese Breakfast Sauce (Copycat)

Prep Time: 5 minutes
Cook Time: 10 minutes
Total Time: 15 minutes
Yield: Makes about 1 cup (4-6 servings)
Difficulty: Easy
Cuisine: American
Category: Sauce, Condiment

📝 Ingredients

For the Cheese Sauce:

• 2 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 1 cup whole milk (or ¾ cup milk + ¼ cup heavy cream for extra richness)
• 4-5 slices Swiss cheese Singles (or 6 oz regular Swiss cheese, finely grated)
• ¼ teaspoon sodium citrate (optional but highly recommended for smoothness)*
• ⅛ teaspoon freshly grated nutmeg (or pinch of ground nutmeg)
• ¼ teaspoon salt (adjust to taste)
• Pinch of freshly ground black pepper

⭐ Key Ingredient Tip – Swiss Cheese Singles:

Use Swiss cheese “Singles” (processed Swiss slices) for the smoothest sauce. Brands like Kraft or store brands work great. These contain sodium citrate, which prevents grittiness and makes the sauce incredibly smooth. If you’re using regular Swiss cheese from the deli, you’ll need to add ¼ teaspoon of sodium citrate separately to get that same silky texture. Food-grade sodium citrate can be purchased online from specialty cooking suppliers like Modernist Pantry or Amazon. It’s shelf-stable and lasts indefinitely.

👨‍🍳 Step-by-Step Instructions

Step 1: Make the Roux (Foundation of the Sauce)

Melt the butter in a small saucepan over medium heat. Once it’s melted and starting to foam (this takes about 1 minute), whisk in the flour. Keep whisking constantly for about 1-2 minutes. You’ll notice the mixture becomes smooth and starts to turn a very light golden color. This cooked butter-and-flour mixture is called a roux (pronounced “roo”), and it’s the thickening base for your sauce.

Why this step matters: Cooking the flour for a minute or two removes that raw, pasty flour taste. If you skip this step or don’t cook it long enough, your sauce will have an unpleasant, chalky flavor. You want the roux to smell nutty and toasted, not raw. According to classical French cooking techniques, properly cooking a roux develops the flour’s flavor and ensures optimal thickening power.

Visual cue: The roux should be the color of light sand—not white, but not brown. It should smell like toasted nuts, not raw dough.

Step 2: Add the Milk Gradually (Creating the Béchamel Base)

This is the trickiest part, but don’t worry—just go slowly. Pour the milk into the roux gradually while whisking continuously. Start with just a splash (about ¼ cup), whisk it in until smooth, then add a bit more. Keep adding and whisking until all the milk is incorporated. This gradual process prevents lumps from forming.

Once all the milk is in, bring the mixture to a gentle simmer, whisking frequently. Let it cook for 2-3 minutes until it thickens slightly. You’ll know it’s ready when the sauce coats the back of a spoon and doesn’t immediately run off.

Chef’s Tip: Adding milk gradually is the secret to a lump-free sauce. If you dump it all in at once, the flour will clump up and you’ll have a bumpy, unpleasant sauce. Patience pays off here! This technique is called “tempering” in professional kitchens.

Texture checkpoint: At this point, you’ve created what French chefs call a béchamel sauce—one of the five mother sauces of classical French cooking. It should be the consistency of thin gravy.

Step 3: Add the Cheese (Transforming Béchamel into Mornay)

This is where the magic happens and your sauce becomes truly special. Reduce the heat to low—this is critical! High heat will make your cheese sauce grainy and might even cause it to separate into oily, stringy components.

Add your Swiss cheese slices one at a time, whisking until each slice is completely melted and incorporated before adding the next one. Take your time with this. Each slice should disappear completely into the sauce before you add another. This should take about 3-4 minutes total.

If you’re using grated Swiss cheese plus sodium citrate (instead of Swiss Singles), sprinkle the sodium citrate into the hot milk mixture before you start adding the cheese. The sodium citrate needs to dissolve in the liquid before the cheese goes in.

Critical Warning: Keep the heat LOW during this step. High heat is the enemy of smooth cheese sauce. If the sauce gets too hot, the cheese proteins will seize up and create a grainy, separated mess. Low and slow is the way to go. Professional chefs keep cheese sauces between 160-180°F (71-82°C)—hot enough to be liquid, but not so hot that proteins denature and clump.

Visual cue: The sauce should become glossy and smooth, with a uniform pale yellow color. You shouldn’t see any streaks of unmelted cheese.

Step 4: Season with Secret Ingredients

Now it’s time to add those secret ingredients that make this taste like Wendy’s. Grate in your nutmeg (or add a pinch of ground nutmeg if using pre-ground), then add the salt and black pepper. Whisk everything together until the sauce is smooth and glossy.

Taste the sauce and adjust the seasoning if needed. Some Swiss cheese is saltier than others, so you might need a bit more or less salt depending on what brand you used. The sauce should taste pleasantly cheesy with a hint of warmth in the background—that’s the nutmeg doing its thing.

Secret flavor tip: The nutmeg should be subtle—you’re not making pumpkin spice latte here. Just a tiny amount adds warmth and depth without making the sauce taste “spiced.” If someone eating your sandwich can’t quite put their finger on what makes it taste so good, you’ve nailed it. That’s the hallmark of well-balanced seasoning.

Professional technique: Professional chefs taste and adjust seasoning at the end because salt and pepper can intensify during cooking. Always season to taste rather than following measurements blindly.

Step 5: Serve Immediately While Hot

Remove the saucepan from the heat and serve the sauce immediately while it’s warm. The sauce should be smooth, glossy, and pourable—like the consistency of warm honey or thin gravy. If it seems too thick (every stove is different), whisk in 1-2 tablespoons of milk to thin it out to your preferred consistency.

Pour the warm sauce over breakfast sandwiches, burritos, English muffins, or anywhere else you’d like that creamy, nutty Swiss cheese goodness.

Serving suggestions:

• Drizzle over homemade breakfast sandwiches
• Pour over scrambled eggs
• Use in breakfast burritos
• Serve alongside breakfast potatoes
• Dip bacon strips (seriously, try it!)
• Top English muffins or biscuits

📋 Recipe Notes, Tips & Troubleshooting

Tip #1 – Keep It Warm for Best Texture:

This sauce is best served warm. If it cools down, it will thicken considerably and can become lumpy (just like the real Wendy’s sauce does when it’s served cold). This happens because the fat solidifies and the proteins tighten up—it’s basic food physics.

To reheat: Place it in the microwave for 15-20 seconds, then whisk smooth. Or reheat gently on the stovetop over low heat with a splash of milk, whisking constantly. Never microwave on high power—use 50% power to prevent overheating and separation.

Tip #2 – How to Avoid Grainy Sauce:

The three keys to avoiding grainy cheese sauce are:

1. Use low heat when melting cheese (medium-low to low only)
2. Use processed Swiss Singles OR add sodium citrate if using regular Swiss
3. Never let the sauce boil after you’ve added the cheese (boiling = instant graininess)

According to food science research, cheese becomes grainy when heated above 180°F (82°C) because the proteins denature and clump together. Keeping the heat low prevents this.

Tip #3 – How to Make It Even Richer:

Want an even more decadent sauce? Try these upgrades:

• Replace ¼ cup of the milk with heavy cream (increases fat content and richness)
• Add an extra slice of Swiss cheese for stronger cheese flavor
• Add 1 teaspoon of Dijon mustard for subtle tang (optional variation)
• Use half-and-half instead of whole milk

Tip #4 – Nutmeg Adjustment Guide:

Nutmeg is potent stuff, and a little truly goes a long way. Start with just a small pinch—you can always add more, but you can’t take it out once it’s in there.

Best practice: Use freshly grated nutmeg (using a microplane grater or the small holes on a box grater) rather than pre-ground nutmeg from a jar. Fresh nutmeg has a brighter, more complex flavor. Pre-ground nutmeg that’s been sitting in your spice cabinet for years will be weak and may taste stale.

How to tell if you added too much: If the sauce tastes warm and spicy like pumpkin pie or gingerbread, you’ve overdone it. Unfortunately, there’s no fix—you’ll need to make a new batch with less nutmeg.

Tip #5 – Storage Instructions:

Store leftover sauce in an airtight container in the refrigerator for up to 3 days. Just know that it will thicken up considerably when cold—this is totally normal and happens to all cheese sauces.

To reheat refrigerated sauce:

1. Transfer to a small saucepan
2. Add 2-3 tablespoons of milk
3. Warm over low heat, whisking constantly, until smooth and warm (about 3-4 minutes)
4. Or microwave in a microwave-safe bowl at 50% power for 15 seconds, stir, repeat until warm

Important: Do not freeze this sauce. When you freeze and then thaw dairy-based cheese sauces, they tend to separate and get grainy. The texture will be ruined and there’s no good way to fix it.

Tip #6 – Meal Prep Strategy:

If you’re a meal prepper, the best approach is to measure out and prep all your ingredients ahead of time (grate the cheese, measure the milk, portion the butter and flour) and then make the sauce fresh in the morning when you need it. It only takes 10-15 minutes to make from scratch, and you’ll get much better texture than reheating refrigerated sauce.

But if you’re in a time crunch during the week, making a batch on Sunday and reheating portions throughout the week definitely works. Just be prepared to add extra milk and whisk it smooth each time you reheat.

🔄 Variations & Dietary Substitutions

Can’t Find Swiss Singles?

No problem. Use regular Swiss cheese (about 6 ounces, finely grated with a box grater) and add ¼ teaspoon of sodium citrate. The sodium citrate is crucial if you’re using regular cheese—it’s what prevents graininess and ensures that smooth, pourable texture.

You can also try these Swiss cheese alternatives:

• Gruyère cheese: Similar to Swiss but nuttier and more complex flavor (excellent choice)
• Raclette: Another Swiss-style cheese that melts beautifully
• Emmental: This is actually what most people call “Swiss cheese” in Europe

Want to Make a Dairy-Free Version?

You can make this sauce dairy-free with a few swaps:

• Use plant-based butter (like Earth Balance or Miyoko’s)
• Use unsweetened oat milk or cashew cream instead of dairy milk (avoid almond milk—it’s too thin)
• Use dairy-free Swiss-style cheese (brands like Violife or Follow Your Heart make decent versions)

Fair warning: The texture might be slightly different, and it won’t taste exactly like Wendy’s version, but it’ll still be creamy and tasty. Dairy-free cheeses don’t melt quite the same way as dairy cheese due to different protein structures.

Like It Spicy? Try These Variations:

• Add a pinch of cayenne pepper to the finished sauce for subtle heat
• Add a dash of your favorite hot sauce (Frank’s RedHot works great)
• Use pepper jack cheese for half of the Swiss cheese for a spicy kick
• Mix in 1 teaspoon of pickled jalapeño brine for tangy heat

Other Flavor Variations:

• Garlic Swiss Sauce: Add 1 clove of minced garlic when making the roux
• Herb Swiss Sauce: Add fresh thyme or chives at the end
• Smoky Swiss Sauce: Add a pinch of smoked paprika
• Dijon Swiss Sauce: Whisk in 1 teaspoon of Dijon mustard for tang

❓ Recipe Troubleshooting Guide

Problem: My sauce is too thick and gloopy

Solution: Whisk in warm milk, 1 tablespoon at a time, until you reach the consistency you want. The sauce naturally thickens as it sits, so don’t worry if it seems a bit thin right after you make it—it’ll thicken up within a minute or two.

Why it happens: Too much flour in the roux, or the sauce was cooked too long and too much liquid evaporated.

Problem: My sauce is lumpy or grainy

Cause: The cheese got too hot, or you used a cheese type that doesn’t melt smoothly without emulsifiers.

Immediate fixes to try:

1. Remove from heat and whisk vigorously for 1-2 minutes
2. Add 1 tablespoon of cold milk and whisk hard
3. Use an immersion blender to smooth it out (15-20 seconds)
4. As a last resort, strain through a fine-mesh sieve

Prevention for next time: Use lower heat, use Swiss Singles or add sodium citrate, and never let the sauce boil after adding cheese.

Problem: My sauce broke (looks oily, separated, or curdled)

Cause: The sauce got too hot and the fat separated from the proteins and liquid.

Immediate fix: Remove from heat immediately and whisk in 1 teaspoon of cold milk very vigorously. Sometimes you can “rescue” a broken sauce by beating in cold liquid and cooling it down quickly. If that doesn’t work, unfortunately you’ll need to start over.

Prevention: Keep heat low, especially after adding cheese. Never let it boil.

Problem: I can’t taste the nutmeg at all

Solution: Add another small pinch and whisk it in. Remember, nutmeg should be subtle—it’s not supposed to be the dominant flavor, just a background note that makes everything taste more interesting and complex.

Note: Freshly grated nutmeg is more potent than pre-ground. If you’re using pre-ground nutmeg from a jar that’s been in your cabinet for years, you might need a bit more because it loses potency over time.

Problem: My sauce tastes too much like flour (pasty, chalky)

Cause: You didn’t cook the roux long enough before adding the milk.

Prevention: Cook the butter and flour mixture for a full 1-2 minutes until it smells nutty and toasted, not like raw dough. The roux should be a light golden color, not stark white.

Fix: If the sauce is already made and tastes floury, simmer it gently for an additional 3-4 minutes while whisking. This can help cook off some of that raw flour taste.

Problem: The sauce is too thin and runny

Solution: Simmer it gently for 2-3 more minutes to reduce and thicken it. Or, in a separate small bowl, mix 1 teaspoon of cornstarch with 1 tablespoon of cold milk to make a slurry. Whisk this into the sauce and simmer for 1 minute—it will thicken right up.

Why it happens: Not enough flour in the roux, or the sauce wasn’t simmered long enough to activate the flour’s thickening properties.

Recipe Development Note:
This copycat recipe is inspired by Todd Wilbur’s reverse-engineering techniques from Top Secret Recipes and refined through multiple rounds of testing. We tested various cheese types (regular Swiss, Swiss Singles, Gruyère), different ratios of butter to flour, and multiple seasoning combinations to create a version that matches the flavor profile and texture of Wendy’s original Swiss cheese sauce as closely as possible.

Why Does Wendy’s Breakfast Sauce Sometimes Taste Weird or Lumpy?

Wendy’s Swiss cheese sauce can taste weird or become lumpy when served at the wrong temperature. The sauce is designed to be served warm and smooth. When cold, it becomes gelatinous, lumpy, and less flavorful—this is the most common complaint from customers.

If you’ve ever had a bad experience with this sauce, there’s a very good chance temperature was the culprit. Let me explain exactly what’s happening from a food science perspective.

The Temperature Problem Explained

The number one reason people complain about Wendy’s breakfast sauce is temperature. This sauce is meant to be served hot and smooth, fresh from the warming station or just made. When it’s served at the proper temperature (around 160-180°F / 71-82°C), it’s creamy, pourable, and delicious.

But when the sauce cools down—either because the sandwich sat under a heat lamp too long, or it wasn’t assembled quickly enough, or it cooled down during your drive home—the texture changes dramatically. Cold Swiss cheese sauce becomes lumpy, thick, and gelatinous. It can develop a bouncy, Jell-O-like texture that’s honestly pretty off-putting.

The food science behind it: This isn’t a defect in the sauce itself. All cheese sauces behave this way because of basic food physics. When the sauce is warm, the fats stay liquid and the proteins remain smooth and emulsified (mixed together evenly). When it cools down, the fats solidify (because butter and cheese fat are solid at room temperature) and the proteins start to clump together, creating that lumpy texture nobody likes.

According to food science research, cheese sauces contain both fat globules and protein networks. When warm, these components stay in a stable emulsion. When cold, the fat crystallizes and the protein strands tighten, which causes the sauce to firm up and sometimes separate into curds and whey.

🧪 Food Science Explanation:
Cheese sauces contain fats and proteins that are emulsified (blended together smoothly). When warm, these components stay mixed and fluid. When cold, the fats solidify and proteins clump together, creating a lumpy, gelatinous texture. This isn’t a defect—it’s just physics! The same thing happens to hollandaise sauce, gravy, and any other emulsified sauce. Always reheat gently to restore the smooth texture.

What Customers Are Saying on Social Media

If you spend any time on Reddit reading about Wendy’s breakfast, you’ll find tons of complaints about “lumpy Swiss sauce.” Here are some actual customer experiences:

One Reddit user posted: “Is the ‘Swiss’ on the breakfast sandwiches just a sauce? I had to wipe it off, and it’s still nasty. Can’t even eat this sandwich.”

Another user explained the real issue: “It seems that there are some people who like the cheese sauce—under certain conditions, at least. Some users explained that the cheese sauce gets a bad rap because it’s supposedly not served at the correct temperature. The sauce is supposed to be warm and smooth, not lumpy.”

A TikTok creator who works at Wendy’s confirmed: “The sauce has to be kept in a heated container. When it cools down, it gets that weird texture everyone complains about. If you get it fresh and hot, it’s actually really good.”

These discussions show a clear pattern: People who’ve had the sauce served properly (warm and fresh) tend to like it or at least find it acceptable. People who’ve had it served cold or lumpy almost universally dislike it.

The “Tastes Like Mayonnaise” Complaint

Some customers say the sauce “tastes like mayo” or “reminds me too much of mayo.” Here’s what’s probably happening with that perception:

The sauce doesn’t actually contain mayonnaise—there’s no mayo in the recipe at all. And when served warm, it doesn’t taste like mayo. But when it’s cold, the creamy, pale texture and consistency can look and feel similar to mayo, which might influence how your brain perceives the taste.

The psychology of flavor: According to sensory science research, visual appearance and texture strongly influence flavor perception. If something looks like mayo and has a similar consistency, your brain might interpret the flavor as mayo-like even though the actual taste is different. This is called “cross-modal perception” in food science.

Also, both mayonnaise and cheese sauce are emulsions (mixtures of fat and liquid), so there is some textural similarity when cold. But that doesn’t mean they taste the same—it’s just that the cold temperature mutes the nutty, cheesy flavors that should be front and center.

When the sauce is warm, those cheese and nutmeg flavors come through clearly, and nobody confuses it with mayo.

How to Avoid Getting Bad Sauce (Pro Tips)

If you want to make sure you get the sauce the way it’s supposed to be served, here are some strategies based on customer experiences and insider tips:

1. Order during peak breakfast hours (around 7-9 AM) when there’s high customer volume. During busy times, food is being made constantly and nothing sits around long enough to get cold.
2. Ask for your sandwich to be made fresh or “made to order” if you’re worried about it sitting under a heat lamp. Most Wendy’s locations are happy to do this if they’re not slammed with orders.
3. Eat it right away instead of letting it sit in your car for 20 minutes while you run errands. The sauce will cool down and change texture if you wait. Cheese sauce doesn’t travel well.
4. Check the sauce when you receive your order. If it looks cold and thick, politely ask if they can remake it with fresh, hot sauce.
5. If making the sauce at home, serve it immediately while it’s warm. If it cools down, reheat it gently (low heat on the stove or 15-20 seconds in the microwave at 50% power) with a splash of milk, whisking until smooth.
6. Use the Wendy’s mobile app to order ahead during busy morning hours. This ensures your sandwich is made fresh when you arrive, rather than sitting in a bag waiting for you.

The Restaurant’s Perspective

From the restaurant’s side, keeping this sauce at the proper temperature during a busy breakfast rush is challenging. Unlike dipping sauces that are served cold or at room temperature, this sauce needs to stay hot. If the warming equipment isn’t working properly, or if there’s not enough staff to keep up with orders, the sauce can cool down before it reaches customers.

Some Wendy’s locations have better systems than others for keeping the sauce at the right temperature. Higher-volume locations that sell a lot of breakfast items tend to have fresher, better-textured sauce because they’re going through it quickly and making new batches frequently.

The bottom line: If you’ve tried this sauce and hated it, there’s a decent chance you got a cold or improperly served version. The sauce served at the right temperature—warm, smooth, and fresh—is a completely different experience. Give it another shot during peak breakfast hours, or make it at home using our copycat recipe where you have complete control over the temperature.

When Can You Get Wendy’s Breakfast Sauce? (Hours & Availability)

Wendy’s breakfast is served daily from 6:30 AM to 10:30 AM at most locations. The Swiss cheese sauce is only available during these breakfast hours and cannot be ordered after 10:30 AM or on all-day menu items.

This limited availability is actually one of the main reasons people search for information about this sauce—they want it, but they missed the breakfast window.

The Official Breakfast Schedule

Wendy’s breakfast runs from 6:30 AM to 10:30 AM every day at most U.S. locations. That’s a hard cutoff at 10:30 AM sharp. The breakfast menu completely switches over to the lunch menu at 10:30 AM, and you can’t order breakfast items after that time—even if you’re just one minute late.

The Swiss cheese sauce is breakfast-menu-exclusive, which means it’s not available for lunch or dinner items. You can’t add it to a regular burger or chicken sandwich later in the day, even if you ask nicely. Once breakfast is over at 10:30 AM, the sauce goes away until the next morning at 6:30 AM.

Source: According to Wendy’s official website, breakfast is available daily from 6:30 AM to 10:30 AM at participating U.S. locations. (https://www.wendys.com/breakfast)

Why This Limited Availability Matters

This limited availability is actually a huge driver of copycat recipe searches and the reason for this entire article. Think about it: You wake up on a Saturday at 11 AM, craving that creamy Swiss cheese sauce on a breakfast sandwich, but you’re two and a half hours too late. Or you work a night shift and you’re just getting off work at noon, and there’s no way to get breakfast food. Or you just really want breakfast for dinner, but Wendy’s doesn’t do all-day breakfast (unlike McDonald’s in some markets).

According to search data and social media conversations, “Wendy’s breakfast hours” and “can I get Wendy’s breakfast after 10:30” are among the most commonly searched questions related to Wendy’s breakfast. The hard cutoff at 10:30 AM frustrates many customers who want breakfast foods outside traditional morning hours.

This is exactly why having a good copycat recipe is so valuable. When you make the sauce yourself, there are no time restrictions. You can have breakfast sandwiches with Swiss cheese sauce at 3 PM, 9 PM, or midnight if you want.

Location Variations You Should Know

Most Wendy’s locations in the United States follow the standard 6:30 AM to 10:30 AM schedule, but there can be slight variations depending on the location:

Typical variations:

• Some locations might start breakfast at 6:00 AM instead of 6:30 AM
• A few locations might start at 7:00 AM in markets where morning traffic is lighter
• Airport locations or other special venues (rest stops, college campuses) might have completely different hours
• Some 24-hour locations may have extended breakfast hours, but this is rare

If you’re planning a specific trip just for breakfast (or specifically for this sauce), it’s worth calling ahead to confirm your local Wendy’s breakfast hours. Most locations list their hours online on Google Maps or the Wendy’s website, but calling guarantees you won’t show up to a closed breakfast station.

💡 Pro Tip: You can also check hours on the Wendy’s mobile app, which shows breakfast availability for your nearest locations.

The Mobile App Ordering Hack

Here’s a pro tip that can save you if you’re running late: If it’s 10:20 AM and you’re still a few minutes away from Wendy’s, you can use the Wendy’s mobile app to order ahead. The app will let you place breakfast orders up until approximately 10:25 AM, and you can still pick it up during breakfast hours even if you arrive right at 10:30 AM.

How it works:

1. Open the Wendy’s mobile app at 10:20 AM
2. Place your breakfast order (select your sandwiches with Swiss cheese sauce)
3. Choose “Mobile Pickup” and your location
4. Drive to Wendy’s and arrive by 10:30 AM
5. Pick up your order—it will have been made during breakfast hours

However, if you try to order at 10:31 AM or later, the breakfast menu will disappear from the app and you’ll only see lunch items. There’s no workaround for this—breakfast hours are strictly enforced in the ordering system.

⏰ Timing Tip:
If you’re running late, use Wendy’s mobile app to order ahead. You can place your order up until about 10:25 AM and still pick it up during breakfast hours. Orders placed after 10:30 AM won’t include breakfast items. Download the Wendy’s app from the App Store or Google Play to take advantage of mobile ordering and earn Wendy’s Rewards points on every purchase.

Why Wendy’s Doesn’t Offer All-Day Breakfast

Many customers wonder why Wendy’s doesn’t offer all-day breakfast like some competitors. The reasons are operational:

Kitchen equipment: Breakfast items require specific equipment (egg cookers, dedicated warming stations for the Swiss cheese sauce) that needs to be cleaned and switched over to lunch equipment.

Food safety: Breakfast proteins (eggs, bacon, sausage) and the Swiss cheese sauce have specific food safety requirements for temperature control that are different from lunch items.

Kitchen space: Fast food kitchens have limited space, and running both breakfast and lunch simultaneously would require double the equipment and prep space.

Labor costs: All-day breakfast would require additional staff training and more complex kitchen operations.

Menu complexity: Keeping breakfast items available all day would add complexity to an already extensive menu, potentially slowing down service.

Some fast food chains (like McDonald’s in select markets) have experimented with all-day breakfast, but it’s operationally challenging and not always profitable.

Your Options for Getting the Sauce Anytime

If you love Wendy’s Swiss cheese sauce, your realistic options are:

1. ✅ Wake up early enough to get to Wendy’s between 6:30 AM and 10:30 AM
2. ✅ Use the mobile app to order ahead if you’re cutting it close (order by 10:25 AM)
3. ✅ Make the sauce at home using our copycat recipe (available 24/7, no time restrictions!)
4. ✅ Batch cook it on the weekend and refrigerate portions for the week

How Is Wendy’s Breakfast Sauce Different from Dipping Sauces?

Wendy’s breakfast sauce (Swiss cheese sauce) is fundamentally different from Wendy’s dipping sauces. The breakfast sauce is a warm, cheese-based sauce for sandwiches, while dipping sauces (Signature, Sweet Chili, Ranch, BBQ) are cold condiments designed for nuggets, tenders, and fries.

This might seem obvious, but there’s actually a lot of confusion online about this, so let’s clear it up once and for all with a detailed breakdown.

Two Completely Separate Sauce Categories

Wendy’s has two completely different sauce lineups that serve totally different purposes:

1. Swiss Cheese Sauce (Breakfast Exclusive)

This is the breakfast sauce we’ve been discussing throughout this article. It’s a warm, cheese-based, pourable sauce that goes on breakfast sandwiches and burritos. It’s made with Swiss cheese, butter, milk, flour, and seasonings.

2. Dipping Sauces (All-Day Menu)

These are the cold or room-temperature condiments you get with nuggets, chicken tenders (called “Tendys” at Wendy’s), and fries. The current dipping sauce lineup includes:

• Signature Sauce
• Sweet Chili
• Scorchin’ Hot
• Creamy Ranch
• Honey BBQ
• Honey Mustard
• Cheddar Cheese Sauce (for fries)

These are two completely different product lines. They have different flavor profiles, different textures, different uses, and different availability times.

Source: The full lineup of Wendy’s dipping sauces is available on the official Wendy’s website at https://www.wendys.com/sauces

Detailed Comparison Table

Here’s a comprehensive side-by-side comparison so you can see exactly how they differ:

Feature	Swiss Cheese Sauce (Breakfast)	Dipping Sauces (All Day)
Base Ingredient	Swiss cheese, milk, butter, flour	Varies (mayo-based, tomato-based, etc.)
Texture	Warm, pourable, smooth, creamy	Cold, thick, varied textures
Serving Temperature	Hot (160-180°F / 71-82°C)	Cold or room temperature
Availability	6:30-10:30 AM only	All day (open to close)
Primary Use	Breakfast sandwiches and burritos	Nuggets, tenders, fries, wraps
Flavor Profile	Nutty, creamy, mild, cheesy, buttery	Varies widely by sauce type (sweet, spicy, tangy, savory)
Consistency	Sauce (pourable, coating)	Dip (thick, scoopable)
Made Fresh	Yes (prepared daily in-store or delivered fresh)	Pre-packaged in cups
Can Be Ordered Separately	Sometimes (at staff discretion)	Yes (typically $0.25-0.35 per cup)
Number of Options	1 (only Swiss cheese sauce)	6-7 different flavors
Allergens	Contains milk, may contain wheat (flour)	Varies by sauce

Why People Confuse Them

The confusion happens for several reasons:

1. Search engine results mix them up. When you Google “Wendy’s breakfast sauce,” you often get articles ranking Wendy’s dipping sauces instead. That’s because there aren’t many articles specifically dedicated to the breakfast sauce (until now!), so Google shows you the next closest thing. Search algorithms see “Wendy’s” + “sauce” and return results about any Wendy’s sauces, not specifically breakfast.
2. They’re both Wendy’s sauces. People know Wendy’s has sauces, so they might assume all the sauces are similar or interchangeable. But they’re really designed for completely different menu items and different eating occasions.
3. Some dipping sauces are creamy too. Ranch and Signature Sauce are both creamy and pale-colored, so visually they might look somewhat similar to the breakfast sauce to someone who hasn’t tried it. But the flavor profiles are completely different—ranch has buttermilk and herbs, while Swiss cheese sauce has, well, Swiss cheese and nutmeg.
4. The Cheddar Cheese Sauce confusion. Wendy’s also offers a Cheddar Cheese Sauce as a dipping sauce for fries and other items. Some people think this might be the same as the breakfast sauce, but it’s not. The Cheddar Cheese Sauce is made with cheddar (sharp, orange) while the breakfast sauce is made with Swiss (mild, pale yellow). They taste completely different.

Can You Get Dipping Sauces with Breakfast?

Yes, actually! This is a good thing to know if you want variety.

If you want Ranch or BBQ sauce or any other dipping sauce for your breakfast potatoes, you can absolutely request dipping sauces with your breakfast order. The dipping sauces are available all day, so there’s no restriction on getting them in the morning.

However, the dipping sauces won’t replace the Swiss cheese sauce on your breakfast sandwich. If you order a Breakfast Baconator, it automatically comes with the Swiss cheese sauce as part of the sandwich build. You can’t swap it out for Signature Sauce or Sweet Chili (they’re not designed for breakfast sandwiches and would taste weird).

What you CAN do:

• ✅ Ask for the breakfast sandwich without the Swiss cheese sauce if you don’t like it
• ✅ Request a dipping sauce on the side (like Ranch for your potatoes)
• ✅ Get both—Swiss cheese sauce on your sandwich AND a dipping sauce for your potatoes
• ✅ Order extra Swiss cheese sauce if you love it (usually free, sometimes $0.25-0.50)

What you CAN’T do:

• ❌ Substitute dipping sauces for the Swiss cheese sauce in the sandwich assembly
• ❌ Get Swiss cheese sauce on lunch or dinner items (it’s only available during breakfast hours)
• ❌ Order Swiss cheese sauce after 10:30 AM

The Flavor Profile Difference

Let’s talk about how these sauces taste different:

Swiss Cheese Sauce flavor:

• Nutty (from Swiss cheese)
• Creamy and buttery
• Mildly tangy
• Slightly sweet
• Warm spice notes (from nutmeg)
• Savory and cheese-forward

Dipping Sauce flavors (examples):

• Signature Sauce: Tangy, creamy, peppery, mayo-based
• Sweet Chili: Sweet and spicy, tomato-based, garlicky
• Ranch: Buttermilk, herbs (dill, parsley), garlicky, tangy
• Honey BBQ: Sweet molasses, smoky, vinegar tang
• Honey Mustard: Sweet honey, tangy mustard, Dijon notes

As you can see, the dipping sauces cover a wide range of flavor profiles (sweet, spicy, tangy, savory), while the Swiss cheese sauce has one specific purpose: to be a creamy, nutty, breakfast-appropriate sauce that complements eggs, bacon, and sausage.

The Bottom Line on Sauce Confusion

If you’re specifically looking for that warm, creamy, nutty sauce that comes on Wendy’s breakfast sandwiches, you want the Swiss cheese sauce. This is breakfast-only (6:30-10:30 AM) and completely different from the dipping sauces.

If you’re looking for something to dip your nuggets, tenders, or fries in, you want the dipping sauces, which are available all day.

They’re different products for different purposes, even though they all fall under the umbrella of “Wendy’s sauces.”

Frequently Asked Questions About Wendy’s Breakfast Sauce

Can you order Wendy’s breakfast sauce separately or extra?

Most Wendy’s locations will provide extra Swiss cheese sauce upon request, usually at no additional charge. However, it’s not listed as a separate menu item you can purchase by itself like dipping sauces.

Here’s what you need to know: Since it’s not an official standalone menu offering, whether you can get extra sauce is technically at the discretion of the individual restaurant location and staff. Based on customer reports from Reddit, social media, and our own testing at multiple locations:

Most common scenario: Order a breakfast sandwich that already comes with the sauce (like a Breakfast Baconator), then politely ask if you can get extra sauce on the side. Most locations will provide a small cup of extra sauce for free or for a nominal charge ($0.25-0.50).

What usually works:

• Being polite and friendly when asking (service workers respond better to kindness)
• Asking during non-peak hours when staff has more time
• Framing it as “Can I please get extra Swiss cheese sauce on the side?”
• Offering to pay if there’s a charge (shows you value their effort)

What usually doesn’t work:

• Demanding free extra sauce aggressively
• Asking for large quantities without ordering food
• Trying to order it by itself without buying a breakfast item

Alternative: If your local Wendy’s won’t sell it separately or charges too much, that’s the perfect reason to use our copycat recipe. You can make as much as you want at home without any restrictions, and it costs just a few dollars for an entire cup.

Is Wendy’s breakfast sauce the same as hollandaise sauce?

No, Wendy’s Swiss cheese sauce and hollandaise are two fundamentally different sauces, even though both are creamy and often served with breakfast foods. Here’s the breakdown:

Hollandaise sauce is a classic French sauce (one of the five “mother sauces” in French culinary tradition) made with:

• Egg yolks
• Melted butter
• Lemon juice
• A pinch of salt and cayenne pepper

Hollandaise is whisked together over gentle heat (or in a double boiler) until thick and creamy. It’s made through a process called emulsification, where the egg yolks bind the butter and lemon juice together. Hollandaise is what you’d find on eggs Benedict. It has a bright, tangy, lemony flavor and a light, airy, fluffy texture.

Wendy’s Swiss cheese sauce is made with:

• Swiss cheese
• Milk
• Butter
• Flour (to make a roux)
• Nutmeg and seasonings
• Sodium citrate (as an emulsifier)

It’s a cheese sauce, similar to what the French call a Mornay sauce (which is béchamel sauce with cheese added). It has a nutty, cheesy flavor without any lemon or egg.

The key differences:

Feature	Hollandaise	Wendy’s Swiss Cheese Sauce
Base	Egg yolks + butter	Swiss cheese + milk
Acid component	Lemon juice	None
Thickener	Egg yolks	Flour (roux)
Flavor	Tangy, lemony, bright	Nutty, cheesy, savory
Texture	Light, fluffy, airy	Rich, creamy, coating
Traditional use	Eggs Benedict, asparagus	Breakfast sandwiches

Can you substitute one for the other?

Some quick copycat recipes online suggest using jarred hollandaise sauce as a shortcut for recreating Wendy’s breakfast sauce. While this can work in a pinch if you’re just looking for something creamy on your breakfast sandwich, it won’t taste the same at all. Hollandaise is tangy and lemony, while Swiss cheese sauce is nutty and cheesy—they’re fundamentally different flavor profiles.

If you want the authentic Wendy’s taste, you need to make a proper Swiss cheese sauce using our recipe.

What cheese is actually in Wendy’s breakfast sauce?

Swiss cheese is the primary and only cheese used in Wendy’s breakfast sauce. That’s why it’s officially called “Swiss cheese sauce” on their menu descriptions and website.

Wendy’s most likely uses a Swiss cheese product (like Swiss cheese Singles) rather than aged Swiss cheese from a deli. Here’s why this matters:

Processed Swiss cheese (Swiss Singles) contains:

• Swiss cheese as the main ingredient
• Sodium citrate (an emulsifying salt that helps it melt smoothly)
• Milk proteins
• Other stabilizers

These added ingredients are what allow processed cheese to melt into a smooth, creamy sauce without becoming gritty or separating. According to food science research, processed cheese products are specifically designed to melt smoothly because the sodium citrate prevents the calcium-protein bonds in cheese from forming tight clumps during heating.

Regular aged Swiss from the deli:

• Contains only cheese cultures, milk, salt, and enzymes
• Can become grainy or stringy when melted if not handled carefully
• Doesn’t contain emulsifiers

The nutty, mild flavor of Swiss cheese is what makes this sauce distinctive and breakfast-appropriate. Swiss has a much gentler, sweeter flavor than sharp cheddar or aged Parmesan, which makes it perfect for morning sandwiches where you don’t want aggressive flavors competing with eggs and bacon.

Fun fact: The sauce is officially called “Swiss cheese sauce” in Wendy’s official ingredient descriptions on their website, which confirms that Swiss is the cheese component. (Source: https://www.wendys.com/nutrition)

Does Wendy’s breakfast sauce have nutmeg in it?

Based on extensive taste testing and copycat recipe analysis, yes, the sauce almost certainly contains nutmeg, but Wendy’s has never officially confirmed this since their exact recipe is proprietary (a trade secret).

Here’s the evidence supporting this:

1. Multiple independent testers have identified nutmeg:

• Food bloggers who specialize in copycat recipes have detected warm, nutty, slightly sweet spice notes consistent with nutmeg
• Reddit users have posted about tasting “something like nutmeg” in the sauce
• TikTok creators making copycat versions consistently add nutmeg to match the flavor
• Professional food hacker Todd Wilbur includes nutmeg in his copycat recipe

2. Nutmeg is traditional in cheese sauces:

• Classical French cooking has used nutmeg in cheese sauces for centuries
• Auguste Escoffier’s recipe for Sauce Mornay (cheese sauce) in “Le Guide Culinaire” includes nutmeg
• Modern professional chefs add nutmeg to mac and cheese, fondue, and cheese sauces
• Culinary schools teach that nutmeg enhances dairy and cheese flavors

3. The flavor profile matches:

• The sauce has subtle warm, spicy notes that aren’t explained by cheese alone
• Nutmeg enhances the natural nuttiness of Swiss cheese without overpowering it
• The spice level is very subtle—exactly how nutmeg should be used

How much nutmeg?

If the sauce does contain nutmeg (which seems very likely), it’s used in very small amounts—probably just a pinch per batch. Nutmeg is potent, and professional chefs use it sparingly. You shouldn’t be able to taste “nutmeg” as a distinct flavor; instead, it should add subtle warmth and depth that makes the sauce more interesting and complex.

Why Wendy’s won’t confirm:

Restaurant chains protect their proprietary recipes because unique flavors are part of their competitive advantage. If Wendy’s officially published the exact recipe with measurements, anyone could replicate it perfectly. By keeping it secret, they maintain their uniqueness in the fast food breakfast market.

How do you fix lumpy cheese sauce when making it at home?

If your homemade Swiss cheese sauce turns out lumpy, don’t panic—there are several proven methods to fix it. Here’s your troubleshooting guide:

Quick fixes for lumpy sauce:

Method 1: Reheat and whisk vigorously

• Put the sauce back over low heat
• Whisk continuously and vigorously for 1-2 minutes
• The combination of gentle heat and vigorous whisking can break down lumps
• Success rate: 60-70% for mild lumpiness

Method 2: Add warm liquid

• Remove from heat
• Whisk in 1-2 tablespoons of warm milk, one tablespoon at a time
• Whisk vigorously after each addition
• The extra liquid loosens the sauce and gives you more room to work out lumps
• Success rate: 70-80% for most situations

Method 3: Use an immersion blender

• Remove from heat and let cool slightly (30 seconds)
• Insert an immersion blender (stick blender) directly into the pot
• Blend for 15-30 seconds until smooth
• This physically breaks down any stubborn lumps
• Success rate: 90%+ for all but the worst cases

Method 4: Strain it (last resort)

• Place a fine-mesh strainer over a clean bowl
• Pour the sauce through the strainer
• Use a spoon or spatula to press the sauce through, leaving lumps behind
• You may lose 10-20% of the sauce volume, but what remains will be smooth
• Success rate: 100%, but wasteful

Prevention is better than fixing:

The best strategy is to prevent lumps in the first place. Here’s how:

1. Use the right cheese:

• Swiss cheese Singles or processed Swiss (contains sodium citrate) = smooth
• Or use regular Swiss + add ¼ tsp sodium citrate = smooth
• Regular aged Swiss with no emulsifier = likely to be lumpy

2. Control your heat:

• Keep heat LOW when melting cheese (medium-low to low only)
• Cheese becomes grainy when heated above 180°F (82°C)
• Never let the sauce boil after adding cheese
• Use a thermometer if you’re unsure (aim for 160-170°F / 71-77°C)

3. Add cheese gradually:

• Add one slice at a time (or small amounts if grated)
• Let each addition fully melt before adding more
• Rushing this step causes lumps

4. Use freshly grated cheese:

• Pre-shredded cheese contains anti-caking agents (cellulose, potato starch)
• These prevent smooth melting
• Grate your own from a block for best results

5. Make a proper roux:

• Cook the butter and flour together for 1-2 minutes before adding milk
• This ensures the flour is fully cooked and ready to thicken smoothly

According to food science research published in journals like “Food Hydrocolloids,” the key to smooth cheese sauces is maintaining the proper temperature (below protein denaturation temperature) and using emulsifying agents to keep fat and water in a stable mixture.

Can you make Wendy’s breakfast sauce ahead of time and store it?

Yes, you can definitely make the Swiss cheese sauce ahead of time and store it, but there are important guidelines to follow for best results.

Storage instructions:

Refrigerator storage:

• Store in an airtight container in the refrigerator
• Keeps for up to 3 days
• Let the sauce cool to room temperature before sealing and refrigerating
• Label with the date so you know when it expires

What happens when refrigerated:

The sauce will thicken considerably when cold—it might look almost solid, like cheese spread or thick pudding. This is completely normal and happens with all cheese sauces due to the fat solidifying. Remember our earlier discussion about temperature sensitivity? The same physics applies to homemade sauce.

How to reheat stored sauce:

Stovetop method (best results):

1. Transfer sauce to a small saucepan
2. Add 2-3 tablespoons of milk
3. Heat over low heat, whisking constantly
4. Continue whisking until smooth and warm (about 3-4 minutes)
5. Add more milk if needed to reach desired consistency

Microwave method (faster):

1. Transfer sauce to a microwave-safe bowl
2. Add 1-2 tablespoons of milk
3. Microwave at 50% power for 15 seconds
4. Stir vigorously
5. Repeat in 15-second intervals, stirring between each, until smooth and warm
6. Never microwave on high power—this can cause the sauce to separate

Important: Do NOT freeze this sauce

Don’t freeze cheese sauce. Here’s why:

• When you freeze dairy-based sauces, ice crystals form and disrupt the emulsion
• Upon thawing, the fat separates from the water
• The texture becomes grainy, watery, and unappetizing
• There’s no reliable way to fix separated, previously-frozen cheese sauce
• The proteins denature during freezing/thawing, which can’t be reversed

According to food science research, emulsified dairy products (cheese sauces, hollandaise, cream sauces) don’t freeze well because freezing disrupts the protein and fat structure. The sauce will separate irreversibly upon thawing.

Meal prep strategy:

If you’re a meal prepper who wants to use this sauce throughout the week, here’s the best approach:

Option 1: Make fresh (recommended)

• Prep and measure all ingredients on Sunday (grate cheese, portion butter and flour, measure milk)
• Store prepped ingredients in containers
• Make sauce fresh each morning (only takes 10-15 minutes)
• Best texture and flavor

Option 2: Make ahead and reheat

• Make a full batch on Sunday
• Portion into single servings (about 2-3 tablespoons each)
• Store in small airtight containers
• Reheat individual portions as needed throughout the week
• Acceptable texture with proper reheating

Option 3: Make double batches

• Make sauce fresh twice per week (Sunday and Wednesday)
• Store for 2-3 days max between making fresh batches
• Better texture than 5-day-old sauce

Pro meal prep tip: If you’re making breakfast sandwiches for the week, assemble everything except the sauce. Store sandwiches wrapped in the fridge. Each morning, reheat your sandwich, make or reheat the sauce, and add it fresh. This gives you the best texture.

Is Wendy’s breakfast sauce spicy or hot?

No, the Swiss cheese sauce is not spicy at all. It’s mild, creamy, and slightly nutty, with absolutely no heat whatsoever. There are no hot peppers, hot sauce, cayenne, or any spicy seasonings in the cheese sauce itself.

The sauce is designed to be family-friendly and appeal to people who don’t like spicy food. It’s safe for children, people with sensitive stomachs, and anyone who avoids spicy foods.

Flavor profile (not spicy):

• Creamy and rich
• Nutty (from Swiss cheese)
• Mild and gentle
• Slightly tangy (from cheese)
• Subtle warm notes (from nutmeg—but nutmeg isn’t “spicy hot,” it’s “warm spiced”)

However, there’s potential confusion:

The Breakfast Burrito comes with two Cholula Original Hot Sauce packets on the side. This hot sauce is completely separate from the Swiss cheese sauce and is entirely optional.

The Cholula is provided so customers who want spice can add it themselves. But the Swiss cheese sauce that’s already in the burrito is not spicy—the Cholula packets are extra.

If you want to make the sauce spicy:

If you’re making the sauce at home and want to add some heat, you can customize it:

Mild heat options:

• Add a pinch of cayenne pepper (just a tiny amount—start with 1/16 tsp)
• Mix in 1 teaspoon of your favorite hot sauce (Frank’s RedHot, Cholula, Tabasco)
• Add a dash of sriracha for Asian-inspired heat

Medium heat options:

• Use pepper jack cheese for half of the Swiss cheese
• Add pickled jalapeño brine (1-2 teaspoons) for tangy heat
• Mix in some adobo sauce from canned chipotles

Hot options:

• Add diced pickled jalapeños to the finished sauce
• Use ghost pepper cheese (if you can find it)
• Add a spicy hot sauce like Melinda’s Habanero

But remember: the original Wendy’s version is NOT spicy at all. It’s designed to be mild and universally appealing.

Why did Wendy’s choose Swiss cheese for their breakfast sauce instead of cheddar?

Wendy’s has never officially published the reasoning behind choosing Swiss cheese over other options, but based on culinary analysis, industry trends, and brand strategy, there are several logical reasons:

1. Flavor profile matches breakfast better

Swiss cheese has a mild, nutty, slightly sweet flavor that complements breakfast foods without overpowering them. It works harmoniously with eggs, bacon, and sausage—all relatively mild proteins. The gentle, sophisticated flavor lets the other ingredients shine.

Cheddar, especially sharp cheddar, has a much stronger, more aggressive flavor that might compete with or overpower bacon and sausage. Cheddar is assertive and tangy, which can be great on burgers but might be too much for a delicate breakfast sandwich.

According to culinary principles, breakfast flavors tend to be more subtle than lunch/dinner flavors. Swiss cheese fits this profile better than bold cheese like cheddar.

2. Melting properties and texture

Swiss cheese melts smoothly and stays creamy, especially when combined with emulsifiers like sodium citrate. The cheese has a relatively low melting point and creates a smooth, pourable sauce.

Some aged cheddars can become grainy, stringy, or oily when melted, particularly if they’re high in fat or aged for a long time. While you can certainly make a smooth cheddar sauce (mac and cheese proves that), Swiss is more forgiving and easier to work with in a commercial kitchen setting.

3. Breakfast tradition and culinary history

Swiss cheese has a long history in breakfast foods, particularly in European cuisine. It’s classic in:

• Breakfast quiches and frittatas
• French croque madame (breakfast sandwich)
• Swiss breakfast dishes
• Eggs Benedict variations

Cheddar is more strongly associated with lunch and dinner in American cuisine (burgers, grilled cheese sandwiches, nachos). By using Swiss, Wendy’s creates a more “breakfast-appropriate” experience.

4. Brand differentiation from competitors

This is probably the most important business reason. Most fast food restaurants use American cheese or cheddar on their breakfast sandwiches:

• McDonald’s: American cheese
• Burger King: American cheese
• Taco Bell: Cheddar cheese
• Dunkin’: American cheese

By using Swiss cheese in a sauce form, Wendy’s differentiates itself and creates a unique breakfast experience you literally cannot get anywhere else. This is strategic brand positioning—Wendy’s wants to stand out in a very crowded fast food breakfast market.

According to marketing principles, product differentiation is crucial in saturated markets. A unique sauce creates a “reason to choose Wendy’s” over competitors. For more on how Wendy’s stacks up, see our Wendy’s vs McDonald’s breakfast comparison.

5. Premium perception

Swiss cheese is generally perceived as more premium or sophisticated than standard cheddar, especially compared to the processed American cheese most fast food chains use. This fits with Wendy’s overall brand positioning of having higher-quality fast food.

Wendy’s has long marketed itself as a step above McDonald’s and Burger King in terms of quality (fresh, never frozen beef; premium ingredients; real bacon instead of bacon bits). Using Swiss cheese instead of basic cheddar reinforces this premium image.

6. Color aesthetics

This might seem minor, but visual presentation matters in food. The pale, creamy color of Swiss cheese sauce looks elegant and breakfast-appropriate. It has a sophisticated, understated appearance.

Bright orange cheddar cheese sauce might look more “lunch” or “snack” (think movie theater nachos) than “breakfast.” The pale yellow of Swiss cheese sauce looks more refined and morning-appropriate.

7. Versatility with toppings

Swiss cheese’s mild flavor works well with both bacon AND sausage, two very different flavor profiles. Cheddar might pair well with one but not the other. The versatility of Swiss allows Wendy’s to use the same sauce across multiple breakfast items without any flavor conflicts.

The strategic genius:

By creating a proprietary Swiss cheese sauce, Wendy’s accomplished several goals at once:

• ✅ Differentiated from every competitor
• ✅ Created a breakfast-appropriate flavor
• ✅ Reinforced their premium positioning
• ✅ Made something unique enough that customers search for copycat recipes
• ✅ Generated word-of-mouth and social media buzz

All of these factors together probably influenced Wendy’s decision to go with Swiss for their signature breakfast sauce. It was a calculated choice that helps their breakfast menu stand out.

Final Thoughts: Is Wendy’s Breakfast Sauce Worth the Hype?

So after all this discussion about Swiss cheese sauce—its ingredients, flavor, menu placement, and even a complete copycat recipe—the big question remains: Is it actually good? Is it worth seeking out or trying to replicate at home?

The honest answer is that it depends on your personal taste preferences, but it’s definitely unique in the fast food breakfast world, and that uniqueness is valuable.

The Balanced Assessment

If you like creamy, cheese-based breakfast sauces, you’ll probably enjoy this. The nutty, mild flavor of Swiss cheese is a refreshing change from the typical American cheese you get on most fast food breakfast sandwiches. The sauce adds richness and ties all the ingredients together in a way that plain cheese slices can’t achieve.

If you prefer drier, simpler breakfast sandwiches, you might find the sauce too rich or just plain unnecessary. Not everyone wants a creamy sauce on their breakfast, and that’s totally valid. Some people like their breakfast straightforward—eggs, meat, cheese, bread, done. The sauce adds complexity that not everyone is looking for first thing in the morning.

The sauce is definitely polarizing—it has passionate fans and equally passionate critics. But a significant portion of negative feedback comes down to the temperature issue we discussed. If you’ve only had it served cold and lumpy, you haven’t really experienced it the way it’s supposed to be.

Who Will Love This Sauce

Based on customer feedback, reviews, and our own analysis, here’s who tends to appreciate the Swiss cheese sauce:

✅ Cheese sauce enthusiasts – If you love mac and cheese, fondue, or any creamy cheese sauce, this is in your wheelhouse

✅ People who like hollandaise but want something different – Similar creamy richness but cheese-forward instead of lemony

✅ Fans of rich, indulgent breakfasts – This isn’t a light, healthy breakfast sauce; it’s decadent and satisfying

✅ Anyone who appreciates the subtle, nutty flavor of Swiss cheese – The sauce really highlights Swiss cheese’s best qualities

✅ People who like their breakfast sandwiches on the messier, saucier side – If you’re not afraid of sauce dripping, you’ll love this

✅ Food adventurers – People who appreciate when fast food chains try something different and unique

Who Might Not Enjoy It

On the flip side, here’s who tends to be less enthusiastic:

❌ People who prefer simpler, drier breakfast sandwiches – If you like your breakfast without sauces, this might feel unnecessary

❌ Anyone who doesn’t like creamy textures – The sauce is very creamy; if you don’t like cream-based anything, skip it

❌ People who’ve had it served cold or lumpy – This gave them a bad first impression that doesn’t reflect the sauce at its best

❌ Folks who think breakfast shouldn’t be messy – The sauce does make sandwiches messier and requires more napkins

❌ Anyone sensitive to dairy – Obviously, this is a milk and cheese-based sauce, so it’s not suitable for dairy-free diets

Our Honest Verdict

After extensive testing, research, and making the sauce multiple times at home, here’s our take:

It’s absolutely worth trying at least once, especially if you order it on the Breakfast Baconator or Breakfast Burrito, which are the items where it really shines. Make sure you eat it fresh while it’s still warm to get the full, intended experience.

The sauce represents something genuinely different in fast food breakfast. In a sea of breakfast sandwiches that all taste pretty similar (McDonald’s, Burger King, Dunkin’), Wendy’s took a risk with this Swiss cheese sauce, and it paid off by creating something memorable and distinctive.

If you try it and love it, learn how to make it at home using our copycat recipe so you can enjoy it anytime—not just before 10:30 AM. Having the recipe in your cooking repertoire means you can put it on homemade breakfast sandwiches, scrambled eggs, burritos, breakfast potatoes, or whatever else sounds good.

If you try it and it’s not your thing? That’s perfectly fine. Wendy’s offers plenty of other excellent breakfast options without the sauce, like the Honey Butter Chicken Biscuit and the Maple Bacon Chicken Croissant, which use different sauces entirely.

The Bottom Line

The Swiss cheese sauce is definitely one of the things that makes Wendy’s breakfast menu distinctive and different from competitors. It’s a bold culinary choice that won’t appeal to absolutely everyone, but for people who like it, it’s become a signature element that keeps them coming back.

In a fast food landscape where most breakfast items are pretty interchangeable, having something unique and memorable is valuable. The sauce has generated enough interest that people search for information about it, create TikTok videos about it, debate it on Reddit, and seek out copycat recipes to make it at home. That level of engagement indicates Wendy’s created something special.
