I found this recipe on the food network's website. Twice smoked potatoes. I've tried it and it's good. All you do is take a potatoe, coat it with oil, then rub it down with seasoning. I used Head Country and a little garlic salt. Then just throw on the pit until they're done. Then, bring them inside and cut them in half long ways. Scoop out the cores and add them to a large bowl. Add seasoning, garlic salt, butter and a little shredded cheese and mix well. Then just scoop back into the potato skins and put back on the pit for about 30 minutes. They turn out really well. Note* I didn't use a lot of smoke because they are pretty absorbent so a very small piece of wood will do.
