Preheat oven to 250. Place the ham in a covered baking dish, flaying out the slices slightly. In a separate bowl, whisk together all of the glaze ingredients and pour over the ham. Separate each slice of ham and put a small amount of glaze in between each slice.

Cover and bake in the oven, with the convection setting, for 90 minutes. Uncover and turn the temperature up to 300, basting every 10 minutes, for another 90 minutes until the ham is glazed.

Remove the ham to a serving platter. Place the roasting pan with the juices in it on high heat and reduce to a syrupy consistency. Pour over the ham and serve warm.
