When it comes to bbq sauce, most of us think of tomato or ketchup based sauces. They can be sweet, vinegary, spicy, or a combination of all three, but would you believe there's a white bbq sauce based not on ketchup or tomatoes, but mayonnaise? Different from any other bbq sauce, this white bbq sauce (aka Alabama white sauce) uses mayo as a base, along with vinegar, sugars and spices. A southern favorite!
