Instructions
- Whisk the mayonnaise, apple cider vinegar, lemon juice, spicy brown mustard, prepared horseradish and Worcestershire sauce in a bowl until smooth.
- Add the brown sugar, kosher salt, white pepper, garlic powder, onion powder and cayenne. Whisk thoroughly until evenly combined and the sugar has dissolved.
- Transfer to a clean airtight container. Refrigerate for 2–4 hours before using; overnight chilling is also an option.
- Stir before serving and taste for seasoning. Serve as a dipping sauce or spoon over cooked barbecue. Keep any sauce used for raw-meat basting separate from the portion served at the table.
Notes
Prep time is an estimate; allow at least 2 hours to chill, or refrigerate overnight. Keep refrigerated until serving. Use a separate portion for brushing raw meat, and keep the serving sauce free of raw-meat contact.
