01 - Preheat oven to 325°F. Position rack in lower third. Remove all packaging and netting from ham. Place ham flat side down in large roasting pan.
02 - Score ham surface in crosshatch pattern, cutting about 1/4 inch deep through the fat layer.
03 - Cover ham loosely with aluminum foil. Bake for 1 1/2 hours.
04 - While ham bakes, whisk maple syrup, Dijon mustard, brown sugar, apple cider vinegar, melted butter, black pepper, and cloves in small saucepan. Simmer over medium heat, stirring occasionally, until slightly thickened, about 5 minutes.
05 - Remove foil from ham. Brush generously with maple Dijon glaze.
06 - Return ham to oven, uncovered. Bake 30-40 minutes, basting every 10-15 minutes with remaining glaze, until ham is glossy and caramelized.
07 - Remove from oven. Let rest for 15 minutes before slicing and serving.
