Thaw ham in refrigerator for 26 to 28 hours until completely thawed.
Remove ham from packaging and place ham on a roasting rack in a roaster pan, cut-side down. Allow ham to come to room temperature on counter for 1 hour.
Preheat oven to 325 degrees Fahrenheit, add a cup of water to the bottom of the roasting pan, and then place in the center rack and cover with aluminum foil.
Bake 60 minutes, then remove foil.
Cook ham for another 30 minutes, uncovered; glaze ham with orange-honey glaze once every 8 minutes (glaze ham 3 times for last 30 minutes of cook time).
Carefully broil the ham for 3 to 5 minutes, until slightly crisp. Watch ham very closely during this step to prevent overcooking.
The internal temperature of the ham should be 140 degrees Fahrenheit via meat thermometer and nicely glazed and lacquered. Allow the ham to rest for about 20 minutes and serve with the remaining glaze on the side.
