So I'm doing a couple pork butts tomorrow. I've done 5-6 before so I'm getting pretty comfortable with process. My neighbor got some good rub from Tennessee other week and offered to me to use. Much appreciated. But then he told me the way to smoke it is to cover the butt in foil the entire time and once it's almost done then remove the foil to crisp it. I've been on this forum awhile and don't recall seeing anyone do that. Thoughts on that process?
