Juice from 1 can of pineapple, juice from 1 jar of marichino cherries, 1 cup brown sugar, 1/4 tsp cloves, 1/4 tsp dry mustard. Put it all in a pot and reduce it down until it thickens.Pour over your ham.
I also heat the cherries and pineapple in a separate pan with a bit of the "glaze" and ham drippings for about 30minutes. So much easier than sticking them all over the ham with tooth picks, lol
