Barbecue sauce (also abbreviated as BBQ sauce) is a sauce used as a marinade, basting, condiment, or topping for meat cooked in the barbecue cooking style, including pork, beef, and chicken. It is a ubiquitous condiment in the Southern United States and is used on many other foods as well.
Ingredients vary depending on area, but most include vinegar or tomato paste (or a combination) as a base, as well as a combination of onion powder, spices such as mustard and black pepper, and sweeteners such as sugar or molasses.
