1. Put garlic, onions, tomato sauce, bay leaves, vinegar, and Worcestershire sauce in a saucepan. Bring to a boil, then reduce heat and simmer, uncovered, for 30 minutes. Stir in oregano, cayenne, and brown sugar. 2. While sauce is simmering, cover ribs with foil, but do not seal, and bake at 450°F. (230°C) for 15 minutes. Reduce heat to 350°F. (180°C) and pour sauce over the meat. Cover again loosely with foil and bake for 45 minutes, basting several times. Uncover and bake 30-40 minutes longer, basting several times until richly glazed.
