Step 1

Remove ham from fridge 1 hour before beginning, to take chill off. Preheat oven to 325°F.

Step 2

Place remaining ingredients in a medium saucepan. Whisk together, to combine, and bring to a simmer on medium-low heat. Cook for 2 minutes (stirring occasionally) or until sauce has slightly thickened. Remove pan from heat source.

Step 3

Lay two large pieces of aluminum foil on counter (overlapping slightly in middle). Place ham in middle of the foil. Brush 1/3 of the brown sugar glaze on, to cover surface of ham. If using spiral sliced ham, let glaze drizzle down between slices. Wrap ham with foil, until well sealed. Place ham in a large baking dish, flat side down. Place dish on middle rack in 325°F oven.

Step 4

Bake at 325°F for 15 minutes for every pound of meat you are cooking, OR until the internal temperature of the ham reaches 100-110°F. As ham weights vary, it is important to follow these guidelines to ensure juicy ham! Remove ham from oven, and TURN up oven temperature to 400°F. Carefully open foil, and pull it slightly away from the meat (but leave it in pan); brush ham with another 1/3 of the brown sugar glaze.

Step 5

Place ham (STILL UNCOVERED) back into 400°F oven. Cook 15-20 minutes more. Remove ham after 15-20 minutes OR when the internal temperature reaches 160°F. Brush ham with remaining 1/3 glaze; seal the foil back up, and let ham rest for 10 minutes (covered), before slicing to allow juices to redistribute through meat. Once "rested", it's ready to slice and serve.
