Preheat oven to 350 degrees F.

In a medium saucepan, heat bourbon, honey, molasses, and marmalade over low heat for 15 minutes- stirring a bit to prevent burning.

Set aside.

With a sharp knife, cut a diamond pattern across the whole ham.

Stud whole cloves across the whole ham.

Spread half of the bourbon glaze over the ham and roast for 2 1/2 - 3 hours, uncovered, until ham reaches an internal temperature of 130 degrees.

Baste occasionally with additional glaze as ham cooks.

Tent ham with foil and let ham stand for 20 minutes before slicing.
