Preheat oven to 325 degrees. Line large baking pan or dutch oven with enough foil to wrap over the top of the ham to form a "tent." Cut incisions in top of ham 1/4" deep, and about 1" apart to form a criss-cross pattern. At each intersection of the criss-cross, place a whole clove. Pour 3/4 cup of bourbon over ham. Bake, covered, for 25 minutes per pound, basting with the bourbon often. Combine sugar, mustard and 1/4 cup of remaining bourbon. Mix well. Remove ham from oven, uncover, and pat the sugar mixture firmly over the ham. Bake sugar-covered ham uncovered, undisturbed (no basting) at 450 degrees for 15-20 minutes more or until sugar has melted and formed a glaze. Remove cloves prior to serving. Goes great with Pineapple Dressing below.
