Cut 3cm deep criss-crosses into the flat side of the ham. In a small bowl mix together the butter and honey. Slather onto the ham making sure to get in the crevices too. Insert cloves into the ham if desired. Place in a roasting pan.
Bake for 4 hours in the preheated oven. Baste every 20 minutes with the drippings. Remove, slice, serve, savor.
