01 - Preheat the oven to 325°F. Position a rack in the lower third of the oven.
02 - Remove all plastic packaging and netting from the ham. Place ham, flat side down, in a large roasting pan.
03 - Score the surface of the ham in a crosshatch pattern, cutting about 1/4 inch deep.
04 - Cover ham loosely with aluminum foil and bake for 1 1/2 hours.
05 - In a small saucepan, whisk together maple syrup, Dijon mustard, brown sugar, apple cider vinegar, melted butter, black pepper, and cloves. Bring to a simmer over medium heat, stirring occasionally, until slightly thickened (about 5 minutes).
06 - After 1 1/2 hours, remove the foil from the ham. Brush generously with the maple Dijon glaze.
07 - Return the ham to the oven, uncovered, and bake for another 30–40 minutes, basting every 10–15 minutes with more glaze, until the ham is glossy and caramelized.
08 - Remove from oven and let rest for 15 minutes before slicing and serving.
