Step 1

In medium sauce pan whisk together brown sugar, mustard, garlic, marmalade, grapefruit juice, rosemary, and salt. Bring to boil over medium heat; reduce to low and simmer 6-8 minutes.

Step 2

Preheat oven to 325˚F. Place ham in large, greased roasting pan. Pour glaze over top of ham, covering as much surface area as possible. Loosely cover with foil and bake for roughly 12 – 15 minutes per pound or until the internal temperature reaches 125˚F. Remove from oven and baste ham with sauce from bottom of pan.

Step 3

Return ham to oven, uncovered, and bake an additional 30-45 minutes, basting ham with sauce from pan every 15 minutes.

Step 4

When ham is finished baking, allow to rest for 10 minutes before carving. Just before serving, spoon any remaining sauce in the pan over the carved ham. Serve warm.
