Take ham out of the refrigerator 2 hours before cooking to allow it to come to room temperature.
Preheat the oven to 325 degrees F.
Place ham in baking dish fat side up.
Combine pineapple juice, brown sugar, and cloves into a small saucepan. Cook on medium heat until it's thick (roughly 15 minutes)
Brush half of the glaze onto the ham. Save the other half for later.
Cover ham with foil and cook for 90 minutes-2 hours (you want the internal temperature to be above 150)
Remove ham and add the remaining glaze. Cook for another 15 minutes or until the internal temperature is above 160.
