Basic Barbecue Sauce
It's no ketchup, but barbecue sauce is a pretty popular condiment on its own. While you can buy it by the bottle on the same aisle as ketchup, making your own is simple -- plus, you can customize it to your tastes. Ketchup makes a good base for a sweet and savory barbecue sauce that you can use on everything from chicken nuggets to ribs.
Whisk all ingredients together in a medium bowl until thoroughly mixed. This sauce tastes better if you allow it to sit refrigerated for a few hours so the flavors can blend. Taste and adjust the seasonings as you like. Store covered in the refrigerator.
