Combine all the ingredients, including the pork, and cook in a heavy, covered casserole in a 325° F oven for 3 hours. Using tongs, remove the ribs from the casserole and arrange them on a broiler pan. Heat the broiler. Pour the juices from the casserole into a bowl and place in the freezer for 10 minutes to hasten the separation of the fat. Remove and discard the fat. Pour the defatted juices into a saucepan; boil over high heat until reduced by half, about 15 minutes. Broil the ribs about 6 inches from the heat until browned. Serve with the sauce.
