Barbecue sauce is a condiment used to add flavor to meat dishes, particularly those cooked using the grilling or barbecue method. The ingredients used to make BBQ sauce can vary, but it typically includes tomato paste, vinegar, sugar, and spices such as mustard, garlic, and onion powder. The sauce can be used as a marinade, basting sauce, or finishing glaze for meats, poultry, and seafood. Some popular BBQ sauce varieties include Kansas City-style, which is thick and sweet with a tomato-based; and Carolina-style, which is thinner and more vinegary with a mustard-based. Other regional variations include Alabama White sauce, Texas-style, and Memphis-style.
