My mother infused flavor into our hams with cloves, brown sugar, mustard and oranges. Those mouth watering aromas would seep out of our oven while it was baking, driving the whole family to distraction.
Preheat oven to 325°F
Remove all plastic wrapping and inserts from ham. Place ham on cutting board.
Place the ham into a large roasting pan and pour the 1/4 cup of orange juice over the ham to cover the bottom of the pan.
Place in 325°F degree oven and bake for 12 minutes per pound, or until meat thermometer inserted into thickest part of ham reads 140°F degrees.
When ham has heated to 140°F degrees, remove from oven. Turn oven up to 400°F degrees.
Return ham to oven, uncovered, for 15 minutes, basting at 5 minute intervals.
Roast until the ham browns to a deep, golden brown.
Remove from oven and let cool.
