Slow cooker method:
Combine melted butter and honey, then massage over ham, getting in between the slices a little. Trim ham if needed, then place in slow cooker.  Cover and cook on LOW 4-5 hours.

Oven method:
Combine melted butter and honey, then massage over ham, getting in between the slices a little. Cover entire ham with foil. Bake in preheated 275 degree F oven for 1 hour and 45 minutes.

At the end of the cooking time, preheat broiler to HIGH, and line a roasting pan with heavy duty aluminum foil. Lining with foil is essential as glaze hardens when cooled making the pan cleanup a nightmare.  

Combine sugar, seasoned salt, onion powder, ground cinnamon, ground nutmeg, ground ginger, ground cloves, paprika and allspice in a small bowl.  Pat half of the sugar mixture over the top of the ham.

Broil for several minutes, until bubbly and caramelized, then remove from oven.

To a small saucepan, add remaining sugar mixture.  Add 3 Tbsp of either water or ham juices from bottom of the slow cooker. Stir, and heat to a boil.  Boil for about a minute, then remove from heat.

Brush or pour glaze over the ham, then broil again for a minute or two (careful… don’t let it burn!). Remove from oven and let ham rest for 5-10 minutes. 

Serve warm or cold and enjoy!
