Score your ham, about ¼” deep in a crosshatch pattern to allow seasonings to penetrate the meat, and apply your choice of seasonings.

Place your seasoned ham in the center of the grate, right over the water pan with the coals on either side. Close the lid on your grill and adjust your vents to maintain a temperature of about 325°F. Add more coals as necessary. Let your ham grill-roast for roughly 15 minutes per pound. Because the ham is already fully cooked, you just need to bring it up to temperature.

When the ham reaches about 120°F, you can apply a sweet glaze. Glazes typically contain a dominant sweet element like honey or maple syrup, cut with mustard and often bourbon or whiskey. Brush the glaze on periodically until the ham reaches a final temperature of 145°F.
