Better Barbecue Sauce

This recipe makes a lot, but the sauce keeps well in the refrigerator or freezer. Since the flavor of the seasonings may dissipate after long cooking, you may need to add more spices near the end of the cooking time. This recipe can be made soy-free by omitting the soy sauce and Worcestershire sauce and using a soy-free sauce (purchased or homemade) or adding some soy-free vegetable broth base or additional salt.
