Preheat oven to 400 degrees. Rinse ham & place in covered roasting pan and heat in oven for 30 minutes. Pour the coke over ham, cover & reduce oven temperature to 225 degrees and cook for 8 hours. Remove, cool, slice & enjoy.
I usually baste a couple of times during the 8 hours but more often I put it in before bedtime to wake up to the smell of ham.
