For 3 pounds center-cut short beef ribs, line the bottom of a roasting pan with coarsely-chopped white onion. Coat ribs in a seasoning mixture of pepper, salt, granulated garlic and cumin in equal amounts. Add another layer of sliced onions, cover and place in a medium oven (300) for three hours. Uncover and bake for 30 minutes. Serve with bread, good mustard, slaw and beans.
