In saucepan, melt butter over medium-high heat. Add onion. Cook, stirring, 3 minutes or until soft. Stir in remaining ingredients except ribs; bring to boil. Reduce heat; simmer, stirring often, 20 minutes. Meanwhile, preheat oven to 375 degrees. Place ribs in single layer in two baking pans. Bake 1 1/2 hours or until tender. Drain and discard drippings from pans. Spread half of the barbeque sauce evenly over the ribs. Reduce heat to 350 degrees. Bake ribs 15 minutes. Turn and brush with remaining sauce. Bake 15 minutes. Serve!
