Barbecued Spare Ribs or Short ribs

5lbs spare ribs or short ribs
2 med. onions sliced
1 Tbls vinegar
2 Tbls Worcestershire
1 Tbls salt
1 tsp paprika
1 tsp chili powder
3/4 cup Ketchup
1/2 tsp red pepper
1/2 tsp black pepper
3/4 cup water
(go easy on the red pepper unless  you like it really hot)

Select meaty spare ribs and have cut in 2" pieces.  Sprinkle with salt, pepper, and flour.  Place in roaster and cover with sliced onions.  Pour over this the sauce made with the remaining ingredients.  Cover and bake in 350 degree oven for 3 hours. (You want the meat to be falling apart, if not, then cook a little longer) Baste occasionally, turning meat over once or twice.  Remove cover during last 15 min. of baking.
