Step 1

Preheat oven to 325 degrees F (165 degrees C).

Step 2

Remove skin and excess fat from ham, leaving a fat layer about 1/4-inch thick. Score ham in a diamond pattern with a sharp knife. Push cloves into the center of the scored diamond shapes. Place ham with cut side down into a roasting pan.

Step 3

Bake ham in the preheated oven until an instant-read meat thermometer inserted into the thickest part of the meat, not touching bone, reads 125 degrees F (52 degrees C), about 2 hours.

Step 4

Combine brown sugar, whiskey, and black pepper in a bowl until glaze is smooth.

Step 5

Raise oven temperature to 375 degrees F (190 degrees C).

Step 6

Baste ham with 1/3 the whiskey glaze. Return to oven and bake until internal temperature reaches 140 degrees F (60 degrees C), basting ham with whiskey glaze every 10 minutes. Cover ham loosely with a tent of aluminum foil if ham browns too quickly.

Step 7

Let ham rest for 15 minutes before carving.
