To prepare: Remove the ham from the refrigerator 1 hour before cooking. Preheat the oven to 350ºF.
Place the ham sliced side up in a large roasting pan. Pour the orange juice and ginger ale overtop the ham.
Cover the pan tightly with aluminum foil and bake for 20 minutes.
In a small bowl, combine the syrup, honey, sugar, mustard and pepper to make the simple glaze. Mix well.
Baste the surface of the ham with juices and brush with ham glaze. Bake again for 20 minutes. (Be sure to leave about 1/2 cup of ham glaze for basting again right before serving.)
Continue baking the ham, basting the outside of the ham with the honey glaze every 15 minutes until the internal temperature of the ham reaches 140 degrees Fahrenheit. The cook time is about 10-15 minutes per pound of fully cooked ham. Plan for about 90-120 minutes of cooking for a ham.
Remove the ham from the oven and allow it to rest covered for 10-15 minutes. Baste with the remaining glaze right before serving.
Other Seasoning ideas: For extra flavor, use pineapple juice and whole cloves.
