Question: how long to cook a 14 lb fully cooked ham?
Answer: Cover with water, bring to the boil and skim away any impurities. Leave the ham to simmer, allowing 20 minutes per 450g(1lb). Pre-heat the oven to 190C/170C Fan/Gas 5. Once cooked, remove the ham from the pan and stand for 10-15 minutes before peeling away the skin.
