SAUCE:

1 med. onion, chopped
1/2 c. butter
1 c. vinegar
1 c. chili sauce
1/3 c. firmly packed brown sugar
2 tsp. lemon juice
1 tsp. Worcestershire sauce
1 tsp. paprika
1/2 tsp. dry mustard
1/2 tsp. chili powder

Saute onion in butter until tender; stir in remaining ingredients and simmer 15 minutes. Use on pork spareribs when grilling. Yield: 3 1/2 cups.

GRILLING SPARERIBS: Cut ribs into serving size pieces. Wash thoroughly. Place in large pot and cook on low for 30 minutes. Drain well.

Grill ribs 5" from heat, over slow coals, 45 minutes or until desired degree of doneness, turning frequently. Brush spareribs with sauce during last 15 minutes. Serve with remaining sauce. Very good.
