This is a generic BBQ sauce probably considered as of the Kansas City variety. It is tangy yet sweet, and can be tempered with more sugar if desired. It does not need to simmer the full time listed in the recipe, but I like it thick as well. This sauce is probably something that you would add near the end of cooking as the sugar can burn, or just serve on the side without putting into the oven or on the grill.
