I score the fat cap on mine, and then smoke with hickory, pecan, or oak. I mix up some pineapple apricot or peach jam with a couple of diced jalapenos and glaze the ham with it a couple of times during the last half hour or so of cook time. The glaze makes a great sauce to serve with the ham. My girls made a batch of Sweet Cherry Jalapeno Lime jam this year. I will be using it on the next ham,
