I do mine in a deep pit (buried in the dirt).....same way they do pigs in Hawaii. I have an old concrete manhole cone that I buried in the ground.... make a big fire the night before....spice it up a little in the morning, as soon as the coals cook down I take the turkey...usually just inject it with apple cider/ butter and some dry rub..... triple wrapped in foil. I throw it in there..... put the metal lid on and cover with wet dirt until I don't see any more smoke....about 6 hours later it's like juicy/buttery/pulled turkey.... don't need nothing fancy like my concrete pit...can just dig a hole about 2.5 deep and build a fire....only difference is you need to do the banana leaves and chicken wire thing to keep the dirt out.
THAT sounds fantastic!
