Alabama White Sauce is an original creation from Robert Gibson of Big Bob Gibson's BBQ out of Decatur, AL. This sauce was made for chicken but people are also using it on pulled pork. I made this sauce because a I was asked to take a shot at making it. I had to test a few versions out and tweak it to my liking. This is my version of the sauce but it has the main parts to the sauce in it. Alabama White Sauce makes 4 cups 2 Cups Mayo 2 Tbsp Horseradish 3/4 cup Distilled White Vinegar 3/4 Cup Apple Cider Vinegar 2 Tsp Black Pepper 1.5 Tbsp Lemon Juice 2 Tsp Kosher Salt 2 Tsp Cayenne Pepper 1 Tbsp Worcestershire Sauce 2 Tbsp Sugar 1 Tbsp Garlic Powder Whisk to mix well. Place in fridge for 2 hours so the flavors blend. Brush on smoked chicken the last 30 minutes of cooking or use as a dipping sauce.
