Make It
Step 1
Combine cola and salt in a medium-size cooler or other 10-quart bucket or stockpot; stir to dissolve the salt.
Step 2
Using a sharp knife, score entire surface of ham in a crosshatch or diamond pattern, cutting down just through the skin. Place ham in the brine, submerging completely. Cover and refrigerate for 12 to 24 hours.
Step 3
Position oven rack in the lowest position and preheat oven to 500° F.
Step 4
Combine parsley, oil, garlic and bouillon in small bowl; stir well.
Step 5
Remove ham from brine. Rinse it well under cold water then pat dry with paper towels. Place the ham wide-side-down in a large roasting pan with a flat rack. Rub outside of ham all over with the bouillon mixture, pressing it gently into scored slices between the skin.
Step 6
Bake uncovered for 20 minutes. Reduce oven temperature to 350° F and continue to bake until the roast reaches 150° F on an instant-read thermometer (this should take 2 to 2 1/2 hours, about 20 to 25 minutes per pound of ham). After the first hour, it’s a good idea to loosely wrap foil around the bone to keep it from burning.
Step 7
Transfer the roast to a carving board and tent with foil; allow the roast to sit at room temperature until the internal roast temperature reaches 160° F (about 20 to 30 minutes). The roast is now ready to carve.
