                        sautéed onion
   1      large   can   peeled tomatoes
                        white vinegar
                        cider vinegar
                        Louisiana dark molasses
                        orange juice
                        lime juice
                        lemon juice
                        dark brown mustard
   2      dashes        Tabasco sauce
                        beef rib rub

Preparation:

After simmering the whole thing for a few (2 to 4) hours, it is run through a puree sieve and served up warm. Man is that a good sauce, especially if you make enough of it to age in the refrigerator for a few weeks. (Don't ask me for the quantities because that varies every time I make it! Just keep adding until its right.
