OK... the first thing you want to do is go to Sam's Club and buy a spiral sliced ham. The price is good on these per pound and they come with a glaze packet. There are instructions on the ham as to how long to bake it, on low heat. About 1/2 hour before it's done, you make the glaze packet per the instructions on it and brush it on the ham.
You will NEVER have as good a ham as this. The glaze is absolutely the best I've tasted.
Aside from getting a Heavenly Ham, it is also the second easiest way to prepare one.
