Calculate cooking time.(Your ham should have it’s own instructions) It’s about 15 minutes per pound, so for example; if you have a 20 pound ham, the cooking time would be 15 minutes for each pound, which would be 4 pounds per hour, which would = 5 hours cooking time
Remove foil 30 minutes before time to take out and give it 15 minutes of resting time before carving.
