Preheat your oven to 325°F (160°C). Remove the ham from its packaging and discard any glaze packet. Place the ham cut-side down on a wire rack in a roasting pan.

In a saucepan over medium-low heat, combine all glaze ingredients and whisk until the sugar dissolves, about 3 minutes. Reserve some for serving later.

Tent the ham with aluminum foil and bake for 60 minutes or until the internal temperature reaches 120°F. Remove foil for the last 15 minutes.

Use a basting brush to apply half of the glaze on the ham's surface, then bake uncovered for 10 minutes. Brush on the rest and bake for another 5 minutes.

Let the ham rest for 10 minutes before carving to allow juices to redistribute. Serve with reserved glaze.
