Mix 3/4 cup mayo ( I used low fat, and it was great), 2 tablespoons apple cider vinegar, 1-2 tablespoons lemon juice (optional see discussion), 2 teaspoons sugar, 1/2 teaspoon table salt, 1/2 teaspoon pepper, 1/2 teaspoon horseradish, and 1/4 teaspoon cayenne pepper.
Refrigerate covered for 1 hour. May store for 2 days.
The sauce here is modeled after an American Test Kitchen/Cooks Country recipe. That recipe had no lemon juice. Most other Alabama White BBQ sauce do. So it is there as an “option”. In practice, I add 1 tablespoon and feel that 2 tablespoons is a bit much. I think ATK was wrong to leave it out.
