1 (12-ounce) bottle chili sauce
¼ cup vinegar
¼ cup Worcestershire sauce
2 cups water
1 medium onion, chopped
Directions to Prep Ribs:
Coat a large nonstick skillet with cooking spray; place over medium high heat until hot. Brown ribs on both sides. Add sherry and ½ cup water.  Cover, reduce heat, and simmer 1-½ hours.
Directions for Prep of Sauce:
Combine salt, celery seeds, and next 8 ingredients in a 2-quart saucepan. Simmer, uncovered, over medium heat 1 hour.
Directions to finish Ribs:
Transfer ribs to a 13x9x2-inch baking dish; pour sauce over the ribs. Bake uncovered, at 300° degrees for 1 hour.
* I'm sending the entire recipe, not just the sauce. This way of cooking the ribs really makes them tender.
