This legendary Alabama white sauce is a tangy, creamy mayonnaise-based condiment that completely transforms barbecue. Originating from north Alabama, it offers a unique alternative to traditional red BBQ sauces with its peppery kick and luxurious texture. The best part? It takes just 5 minutes to make with pantry staples you already have.
Add mayonnaise to a medium mixing bowl, then measure and add the apple cider vinegar, fresh lemon juice, horseradish, and Dijon mustard.
Add black pepper, garlic powder, onion powder, salt, cayenne pepper, and sugar (if using) to the bowl.
Whisk all ingredients together vigorously for about 30 seconds until completely smooth with no lumps of spices remaining.
Taste and adjust seasonings as needed - add more mayonnaise or sugar if too tangy, more pepper or cayenne for extra heat, or water to thin if too thick.
Transfer to a storage container, press plastic wrap directly onto the surface, and refrigerate for at least 30 minutes before serving. Stir before using.
Notes
Use full-fat mayonnaise for best results - low-fat versions make the sauce watery and bland
Freshly ground black pepper makes a significant difference in flavor compared to pre-ground
The sauce improves after sitting in the fridge for a few hours as flavors meld together
Store in an airtight container in the refrigerator for up to 2 weeks
The sauce will thicken as it sits - thin with water one teaspoon at a time if needed
Do not freeze this sauce as the mayonnaise will separate and become grainy
Start with less cayenne than you think you need - you can always add more
Duke's mayonnaise is the gold standard for this sauce and what Alabama pitmasters use
Perfect for smoked chicken, pulled pork, coleslaw, grilled vegetables, and as a sandwich spread
Always use a clean spoon when serving to prevent contamination and extend shelf life
