This “secret sauce” can be made a day ahead—in fact, we recommend that you do that, to help those flavors marry well together. (It’s called “Comeback Sauce” because they keep comin’ back for more!)

Ingredients

　　1/4 cup sour cream

　　2 tablespoons mayonnaise

　　2 tablespoons buttermilk

　　2 tablespoons Neely’s BBQ sauce (see page 37)

　　Juice of 1/2 lemon

　　1/4 teaspoon cayenne pepper

　　Kosher salt and freshly ground black pepper

　　Mix all the ingredients together in a small bowl. Let the sauce sit in the refrigerator as long as possible to let the flavors marry, or make the day ahead.
