Puff, if you are going to smoke a spiral sliced ham, I would try the cheesecloth method mentioned above by OSD to avoid drying out the ham. Spiral sliced hams are not my ham of choice when it comes to double smoking. I always use the Dr. Chicken's Double Smoked Ham method found in our recipie section using a whole bone in hamand don't forget to make the Sweet Kiss of Death injectable marinade.
