Place the ham cut side down in a roasting pan cover tightly with foil paper. Sprinkle with about 3/4 cup brown sugar
Place in a preheated oven and roast for 10 to 12 minutes per pound.
During the last 30 minutes of cooking time the glaze should be applied.
Add remaining brown sugar, mustard, orange and pineapple juice, all spice, nutmeg , ginger, rum, , lemon juice, and cloves to a small saucepan. Bring to a boil and simmer for about 5 minutes or more until it’s syrupy.
Brush with glaze and bake for an additional 15- 20 minutes (basting ham every 10 minutes.) depending on the size of your ham or until an instant read thermometer registers 120°F when inserted into thickest portion of ham.
Remove from the oven to a serving platter and let rest for 15 minutes before serving. Serve with a side of glaze.
