Preheat your oven to 325°F (160°C).
Unwrap the 6 pounds Smoked Ham and place it cut-side down in a large roasting pan. If desired, lightly score the fat with a knife in a diamond pattern, and insert Whole Cloves into the ham at the corners of the diamonds.
In a small bowl, whisk together the 1 cup Brown Sugar, 1/2 cup Pineapple Juice, melted 1/4 cup Butter, and 1 tablespoon Dry Mustard until the mixture is smooth. This is your simple Amish glaze.
Pour about half of the glaze evenly over the ham.
Bake for approximately 15 minutes per pound. (A 6-pound ham bakes for about 1.5 hours.)
After the first hour of baking, begin basting the ham with the pan juices every 15–20 minutes to keep it moist and allow the glaze to caramelize.
During the last 20 minutes of baking, pour the remaining glaze over the ham to create a thick, sticky crust.
The ham is fully cooked and ready when the internal temperature reaches 140°F (60°C).
Carefully remove the ham from the oven and cover it loosely with foil. Let the ham rest for 15–20 minutes before carving. This step is essential to keep all the juices locked inside!
Carve and serve immediately with the pan juices spooned over the slices.
