Preheat oven to 350 degrees F.

Unwrap ham and add to a large roasting dish, skin side up.

Bake uncovered until the internal temperature reaches 150 degrees, about 18-20 minutes per pound.

About 10 minutes before the ham reaches temperature start making your glaze.

In a large skillet add pineapple juice, bourbon, maple syrup, and dark brown sugar.

Simmer until the glaze is cooked down by about half. It should be slightly thick.

Add in butter and stir to combine. Remove from the heat and set aside while you get the ham out of the oven.

Take ham from the oven, remove the skin (it should pull off easily), and score the fat in a criss-cross pattern.

Baste on half the glaze, return to the oven, bake for 15 minutes, re-glaze the ham with the remaining glaze, and bake for another 15 minutes.

Remove the ham from the oven, and let rest for 10 minutes before slicing.
