Take the ham out of the fridge 1 hour before baking. Heat the oven to 325°F (165°C).
Place the ham cut side down in a roasting pan, add 1/2 cup water and cover tightly with foil.
Bake 12 to 15 minutes per pound, until the center (not touching the bone) reaches 120°F (49°C). About 1 hour 50 minutes for a 9 lb ham.
Meanwhile, simmer the brown sugar, honey, mustard, orange juice and cloves in a small saucepan for 2 to 3 minutes until smooth.
Turn the oven to 400°F (200°C). Uncover the ham and brush with half the glaze.
Bake uncovered 15 to 20 minutes, brushing with the rest of the glaze halfway, until caramelized and the center reaches 140°F (60°C).
Rest 15 minutes, then slice and spoon the pan juices over the top.
