Mandarin Spareribs
Yield: 4 to 6 servings

4 to 5 pounds spareribs
1 cup soy sauce
1 cup orange marmalade
3 cloves garlic, minced
1 teaspoon ginger
Black pepper

Combine soy sauce, marmalade, garlic, ginger, and black pepper. Spread spareribs in baking pan. Pour sauce over ribs. Turn ribs to cover completely with sauce. Keep in refrigerator at least 12 hours. Arrange ribs on a rack in a roasting pan. Roast in a moderate oven (350°F.) for 1 1/2 hours, basting frequently with sauce until ribs are glazed golden brown and meat is very tender. Cut the ribs into serving pieces. NOTE: Ribs cut into finger-sized pieces are often finished in a broiling oven to be served as an appetizer.
