Pineapple ham

INGREDIENTS
1 (12 pound) ham
1/2 cup whole cloves
1/2 cup packed brown sugar
1 (20 ounce) can pineapple rings in heavy syrup
1 (4 ounce) jar maraschino cherries

DIRECTIONS
Preheat the oven to 325 degrees F (160 degrees C).
Place ham in a roasting pan. Score the rind of the ham with a diamond pattern. Press a clove into the center of each diamond. Drain the juice from the pineapple rings into a medium bowl, and stir in the brown sugar. Coat the ham with this mixture. Arrange the pineapple rings over the outside of the ham. Place a maraschino cherry in the center of each pineapple ring, and secure with a toothpick. Bake uncovered for 4 to 5 hours, basting frequently with the juices, until the internal temperature of the ham is 160 degrees F (72 degrees C). Be sure the meat thermometer is not touching the bone. Remove toothpicks before serving.
