1 tsp. oil
1 med. onion, chopped (1/2 c.)
1/2 c. ketchup
1/2 c. water
2 tbsp. vinegar
2 tbsp. chili powder
1 1/2 tsp. Worcestershire sauce
1/4 tsp. crushed celery seed or 1/2 tsp. celery flakes
Sometimes I add 2 tbsp. apricot jam
1 (3 lb.) broiler or fryer, skinned and cut into serving pieces

Heat the oil in a large skillet. Add onions. Cook until softened. Stir in all other ingredients. Bring sauce to a boil. Add chicken placing what used to be skin side down. Spoon sauce over pieces. Cover. Simmer for 30 minutes. Uncover and cook "skin side" up 15 minutes or until tender.
