ok, one tip from me, if you are using lump charcoal such as Royal oak, dont use any wood chunks or chips because the lump charcoal is made from hickory, mapple, and oak. if you add additional wood chunks, you will over smoke the thing.
also, the salt content in this recipe is a we bit less than normal since it has to be under the daily recomended portion size in order to be published.. haha. so add salt to taste. i hope this helps you two out.
