If ham has skin, peel it away using a sharp knife and discard, leaving a thin (1/8-inch) layer of fat on the surface. Score remaining fat with a sharp knife by cutting diagonal lines, about 1/8-inch deep, from 1 side to the other, criss-crossing cuts to form diamond shapes on the surface. Transfer ham to a foil-lined roasting pan and set aside.
Whisk together honey, mustard and cloves. Brush mixture all over ham. Pour the Mandarin oranges with liquid from can over the ham.
Bake 1 hour (14 minutes per pound), basting every 15 minutes with pan juices.
Let stand 10 to 15 minutes before slicing into thin slices.
