Preheat the Oven: Preheat your oven to 325°F (165°C). Place the ham cut side down in a rimmed baking sheet or roasting pan lined with foil to make cleanup easier.
1 fully cooked bone-in whole ham
Prepare the Glaze: In a small saucepan over medium heat, combine the brown sugar, maple syrup, Dijon mustard, orange juice, ground cinnamon, ground cloves, and nutmeg. Stir until the sugar dissolves and the mixture thickens slightly, about 5-7 minutes. Remove from heat.
1 ¼ cups light brown sugar, ½ cup maple syrup, ¼ cup Dijon mustard, ¼ cup orange juice, ½ teaspoon ground cinnamon, ¼ teaspoon ground cloves, ¼ teaspoon ground nutmeg
Score the Ham (Optional): If you're using a whole ham, score the surface in a diamond pattern about ¼ -inch deep.
Bake the Ham: Cover the ham loosely with foil and bake for about 15 minutes per pound, or until it reaches an internal temperature of 140°F (60°C). This typically takes 1 ½ to 2 ½ hours.
Apply the Glaze: About 45 minutes before the ham is done, remove the foil. Brush the ham generously with the glaze, then continue baking uncovered. Reapply the glaze every 10-15 minutes, allowing it to caramelize on the surface.
Rest and Serve: Once cooked, remove the ham from the oven and let it rest for 10-15 minutes before slicing.
