Step 1

Thaw the ham. If the ham is frozen, allow it to thaw in the fridge for 1 to 2 days. Then, remove the ham from the fridge and let it rest on the counter for 2 hours before cooking, to come to room temperature.

Step 2

Prep the roasting pan. Preheat oven to 300°F (150°C). Adjust oven rack to lowest position. Pour 2 cups of water into bottom of roasting pan.

Step 3

Mix the honey glaze. In a medium bowl, stir together the sugar, honey, orange juice, mustard, and spices.

Step 4

Brush on the glaze and bake the ham. Place the ham on the baking tray, brush ¼ of the honey glaze on top, then cover the ham with aluminum foil and bake for 10 to 12 minutes per pound (for a 9 pound ham, that's about 1 ½ hours). During this 1 ½ hours you'll re-glaze every 30 minutes.

Step 5

Caramelize the glaze. After 1 ½ hours, increase the oven temperature to 425°F (220°C), discard the aluminum foil, and brush the remaining ¼ of the glaze all over the ham. Return the ham to the oven and bake uncovered for 15 to 20 minutes, until shiny, glazed, and slightly caramelized.

Step 6

Slice the ham. Let the ham rest for a few minutes before serving, then slice it up by removing the spiral slices from the flat, wider end first.
