Preheat oven to 325°F.

Remove packaging; reserve liquid. Place ham cut-side down on large sheet of foil in roasting pan, pour reserved liquid over ham and wrap completely with foil. Warm ham in oven for 10 to 12 minutes per pound. Do not overheat.

After removing from oven, let sit for 5 minutes before glazing. Heat glaze packet for 15 seconds in microwave. Glaze is hot, so be careful when opening packet. Holding packet with towel or oven mitt, cut corner off packet and pour glaze into bowl. Stir well and spoon over ham. Let glazed ham sit for 5 minutes before serving to allow glaze to melt over ham.
