Preheat oven to 325°F (165°C).

Place ham, cut-side down, in a roasting pan and cover tightly with foil.

Bake for 1½ to 2 hours, or until heated through, basting occasionally.

In the last 20–30 minutes, remove foil and brush generously with your glaze.

Return to the oven uncovered, basting every 10 minutes, until the glaze is caramelized and glossy.

Let rest for 10–15 minutes before slicing and serving.
