This tangy white sauce is a Carolina BBQ staple that transforms any grilled meat with its creamy, vinegar-kissed flavor. It’s the perfect balance of richness and acidity.
With just a handful of pantry staples, you can whip up a batch in 5 minutes. Store it in the fridge for up to a week—it only gets better with time.
Ingredients for Carolina White Sauce
Nine simple ingredients make this tangy, creamy BBQ sauce come alive.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥫 | 2 cups | Full-fat for creaminess |
| Apple Cider Vinegar 🍏 | ½ cup | 5% acidity preferred |
| White Sugar 🧂 | ¼ cup | Granulated for sweetness |
| Prepared Horseradish 🌶️ | 2 tbsp | Adjust for heat preference |
| Dijon Mustard 🟡 | 1 tbsp | Smooth texture preferred |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | Not garlic salt |
| Onion Powder 🧅 | ½ tsp | Balances the tang |
The mayonnaise base is key here. Duke’s or Hellmann’s give that classic rich texture—avoid low-fat versions, they break too easily. Apple cider vinegar needs to be 5% acidity for the right tang. I grab mine from Trader Joe’s or Whole Foods. Horseradish adds the kick, so fresh refrigerated has more punch than shelf-stable. Don’t skip it.
No horseradish? White vinegar plus extra black pepper works in a pinch (but it’s not the same). Out of Dijon? Yellow mustard at double the amount gets you close. Sugar can be swapped for honey or maple syrup if you want a natural sweetener. The garlic and onion powders are subtle but important—fresh minced at half the amount if that’s what you’ve got.
This keeps 7-10 days in the fridge. The flavors meld and mellow over time. Freezes for 3 months if you want to make a big batch. Give it a stir before using—separation is normal.

Step-by-Step Instructions for Carolina White Sauce
This comes together in minutes with no cooking required—just whisk and taste as you go.
Step 1: Combine Mayonnaise and Vinegar Base
In a medium bowl, add the 2 cups Mayonnaise and 0.5 cup Apple Cider Vinegar. I always use full-fat mayonnaise here because it gives the sauce that classic rich, creamy texture that clings perfectly to pulled pork.
Whisk these two together for about 30 seconds until fully combined and smooth. You’ll notice the mixture lightens slightly in color as the vinegar incorporates. Real talk: this is the foundation—get this right and the rest is easy.
Step 2: Sweeten and Add Depth
Next, add the 0.25 cup White Sugar, 1 tbsp Dijon Mustard, and 2 tbsp Prepared Horseradish. The mustard adds a subtle complexity, while the horseradish brings that signature kick Alabama white sauce is known for.
Whisk vigorously for another 30-45 seconds until the sugar fully dissolves and the horseradish is evenly distributed. Here’s the thing—if you taste now, it might seem a bit sharp. That’s normal; the sweetness will balance it out as you go.
Step 3: Season and Finish
Add the 1 tsp Salt, 0.5 tsp Black Pepper, 0.5 tsp Garlic Powder, and 0.5 tsp Onion Powder. These dry ingredients tie everything together, enhancing the tangy-sweet profile without overpowering it.
Whisk one final time for 20-30 seconds until completely smooth. The sauce should be thick but pourable, with a glossy sheen. I like to let it sit for 5-10 minutes before using to allow the flavors to meld. This ensures every bite of your BBQ carries that perfect balance of creamy, tangy, and slightly sweet.
Step 4: Adjust and Store
Taste and adjust the seasoning if needed. If it’s too sharp, add a touch more sugar. If it’s too thick, whisk in a teaspoon of water at a time until it reaches your desired consistency. Remember, the horseradish will mellow slightly over time.
Transfer to an airtight container and store in the refrigerator for up to 1 week. The flavors actually improve after a day or two. This makes enough to generously coat pulled pork for 4 servings, with a little extra for dipping.
Pro Tips For Making Carolina White Sauce
- Whisk, Don’t Stir: Use a wire whisk instead of a spoon to blend the mayo and vinegar—this emulsifies the sauce better and prevents that oily separation that ruins the texture.
- Chill the Mayo: Take the mayonnaise out of the fridge 10 minutes before mixing, but don’t let it get warm—cold mayo holds the sauce together, but straight-from-the-fridge makes it too thick to blend smoothly.
- Tame the Horseradish: Drain the prepared horseradish in a fine mesh strainer for 30 seconds to remove excess liquid, otherwise your sauce will turn watery and lose that sharp, tangy kick.
- Sweeten Gradually: Add the sugar in 1/2 teaspoon increments and taste between each—I learned this the hard way after over-sweetening a batch and having to start over.
Essential Equipment for This Dish
Mixing Bowls
A medium stainless steel mixing bowl (about 3-4 quarts) is perfect for whisking this sauce together. I use my Cuisinox bowl—it’s durable and the perfect size. Avoid plastic if possible, as vinegar can absorb odors over time.
Whisk Selection
A balloon whisk works best here because it aerates the sauce slightly while combining ingredients. My go-to is the OXO Good Grips 11-inch. The long handle gives excellent control, and the stainless steel wires won’t bend or rust.
Measuring Tools
For accuracy, I recommend a set of nested measuring cups and spoons. The Pyrex 4-piece glass set is my favorite for liquids like vinegar. For dry ingredients, stainless steel measuring spoons from 1 tsp to 1 tbsp are essential.
Storage Containers
Transfer your finished sauce to an airtight container with a tight-sealing lid. I love Ball Mason jars (pint size) for this—they’re leak-proof and easy to clean. Leave ½ inch headspace to prevent spills when stirring. 💡
Optional Equipment
A small fine-mesh strainer can help if your horseradish has chunks you’d prefer to remove. For large batches, a hand-held immersion blender makes quick work of smoothing everything out.
Cleanup Tip
Have a damp towel ready to wipe up any spills immediately—vinegar can be corrosive to some countertop materials. I also recommend washing your whisk and bowl right after use to prevent the sauce from hardening on them. ❄️

Frequently Asked Questions
Can I use a different type of vinegar?
Stick with apple cider vinegar for authentic flavor, but white vinegar works in a pinch. Avoid balsamic or red wine vinegar—they’ll overpower the sauce.
How do I make it less spicy?
Reduce the horseradish to 1 tbsp or omit it entirely. For mild heat, use prepared horseradish sauce instead of the pure version. The tang remains, but the kick softens.
Does this sauce need refrigeration?
Yes, always store it in the fridge. It keeps for 7-10 days in an airtight container. Freezing isn’t recommended—mayonnaise can separate.
What’s the best way to use it?
Drizzle over pulled pork or chicken, or serve as a dip for fries. It’s also great on burgers or as a salad dressing base. The versatility shines!
