The glaze I used for the ham this year couldn't be simpler, and it's yummy, to boot. Any amount of brown sugar, honey, butter, and cloves could be used, depending on which flavor you want to be most pronounced, and a bit of ground mustard could also be added.
1/2 cup packed brown sugar
1/3 cup honey
1/4 cup butter
1/4 tsp. cloves, plus more to taste
a few smidges of ground mustard
Increase these amounts depending on the size of your ham, and before placing ham into the oven, stud it all over with whole cloves.
Combine all ingredients in a saucepan over medium heat and cook, while stirring, until butter is melted and sugar is dissolved.
Baste the ham with the glaze before placing in the oven and continue to baste about every fifteen minutes until the ham is done. (I wasn't home to do this, so I just basted it once at the beginning and then liberally slapped more on when I got home for the last 1/2 hour of cooking.) The heat may be turned up for the last ten minutes or so of cooking time if the glaze hasn't caramelized sufficiently.
