My brother, Tim, and his girlfriend, Kristen, gave us a ham when we went to PA for Christmas. I took a few slices of it out of the freezer and mixed the following:
1 tablespoon of orange juice, 1/8 teaspoon cinnamon, and about 1 tablespoon of honey.
I baked the ham for about 20 mins, poured the glaze on it, and baked it another 20 mins.
I've probably tried at least 10 ham glazes and this was definitely one of my favorites.
Here is the original recipe, for an 8 lb ham. (with a lot more ingredients)
