Preheat oven to 325*. If ham has skin, peel it away using a sharp knife and discard. Score with a sharp knife by cutting diagonal lines: about ½-inch deep. Transfer ham to a foil-lined roasting pan and set aside. Whisk together honey, mustard and cloves. Brush over entire ham. Pour mandarin oranges with liquid over ham. Bake for 1 hour or 14 minutes per pound. Baste every 15 minutes with juices.
