Old-Fashioned Ham with Brown Sugar and Mustard Glaze

Preheat oven to 325°F. Place ham in large roasting pan. Pour apple juice over ham. Cover ham completely with parchment paper, then cover ham and roasting pan completely with heavy-duty foil, sealing tightly at edges of pan. Bake ham until instant-read thermometer inserted into center of ham registers 145°F, about 3 hours 45 minutes. Remove ham from oven. Increase oven temperature to 375°F.

Remove foil and parchment from ham. Drain and discard liquids from roasting pan. Cut off rind and all but 1/4-inch-thick layer of fat from ham and discard. Using long sharp knife, score fat in 1-inch-wide, 1/4-inch-deep diamond pattern. Spread mustard evenly over fat layer on ham. Pat brown sugar over mustard coating, pressing firmly to adhere. Drizzle honey evenly over. Bake until ham is well glazed, spooning any mustard and sugar glaze that slides into roasting pan back over ham, about 30 minutes. Transfer ham to serving platter; let cool at least 45 minutes. Slice ham and serve slightly warm or at room temperature.
