8 oz. white vinegar
8 oz. water
4 tbsp. worcestershire sauce
4 tbsp. chili powder (cut this with a little cayenne for spicier sauce)
1 rounded tsp. black pepper
4-5 cloves minced garlic
2 cans condensed cream of tomato soup, undiluted
4 tbsp. sugar or equivalent in sweetener (I used six drops EZ-Sweetz liquid)
Combine vinegar, water, worcestershire sauce, chili powder, pepper & garlic; bring to boiling, reduce heat and simmer for five minutes.
Add soup & sweetener, blend well, slather on pork ribs before grilling (this amount will do 2 or 3 large slabs of ribs), and baste at 45 minutes intervals until done, about 2-2½ hours. (this works fine if you're using a rib rack on your grill; if the slabs must be grilled flat on the grill, wait until the last hour of cooking to brush on the sauce.)
