1 small onion or 1/2 medium
1 tsp. garlic powder
1/2 tsp. salt
1 tbsp. olive oil
1 tsp. red wine vinegar
1 cup water or beef broth
1/3 cup ketchup
1 tsp. chili powder
3 tbsp. dry mustard
1 1/2 to 3 lbs. ribs
In a saucepan, combine all ingredients except ribs. Bring to a boil, reduce heat to a simmer and cook over low heat until thickened; allow to cool.
Place ribs in a large, flat pan. Season with salt and pepper, and a little garlic powder on both sides.
Roast in oven at 350°F for about 1 hour. Drain any grease that has accumulated. Cover the roasted ribs with sauce and bake for an additional 45 minutes or until the ribs are tender, basting occasionally as needed.
