Baked Ham with Orange Glaze

1/2 bone-in fully cooked lean ham (6 to 7 pounds)
2 cups apple cider or unsweetened juice
2 cups orange juice
1/3 cup orange marmalade
1/4 cup packed brown sugar
1/4 cup Dijon mustard
1/4 teaspoon ground ginger

Place ham on a rack in a shallow roasting pan. Score the surface of the ham, making diamond shapes 1/4 in. deep. Add cider and orange juice to pan. Loosely cover ham with foil; bake at 325° for 1 hour. Meanwhile, combine remaining ingredients; brush some over ham.

Bake, uncovered, 50-60 minutes longer or until a meat thermometer reads 140° and ham is heated through, brushing occasionally with glaze. Let stand for 15 minutes before slicing. Serve with remaining glaze. Makes 10 servings.
