Heat ham by desired method. My method is in the post.

Heat the glaze ingredients in a small saucepan too boiling. Reduce heat to low and simmer until glaze is slightly thick and syrupy; about 5-8 minutes.

Heat oven to 400F/200C. Bush ham with some glaze and cook ham until glaze begin to caramelize, basting frequently with more glaze during cook time. Ham should cook about 10-15 minutes basting periodically.
