Preheat oven to 275 degrees.

Remove ham from packaging and enclose, cut side down, securely in a large piece of heavy duty foil. Close the foil so that it will open from the top. Place on a rack in a large roasting pan. Pour about 1 of water into the bottom of the roasting pan and place the pan in the preheated oven. Bake for 15 minutes per pound until heated through. A 10 pound ham will takeFor a 7 to 9 pound ham the cooking time take about 90 minutes. Check periodically and add more water to pan if it cooks off.

Meanwhile, whisk together glaze ingredients in a saucepan over medium heat. Allow to simmer for a couple of minutes, then remove from the heat and set aside.

After cooking time, remove pan from oven and increase oven temperature to 400 degrees. Open foil to expose ham and pour glaze evenly over the top. Return the pan to oven for an additional 15 to 20 minutes, or just until glaze has caramelized. Remove from oven and allow to sit for 10 minutes before slicing and serving. Spoon the cooking liquid that has been captured in the foil over the ham as it rests.
