Have you done ribs? I like ribs but not sure they can ever be *that* good however you see loads of people raving about them.
trim them up, mustard and dry rub on each side and then 1 1/2 hours at 275F spritzing with apple juice and cider vinegar
then in foil with more mustard, rub and apple juice and back on for another 1 1/2 hours
then out of the foil, brush with sauce and another 1/2 hr
That seemed to be the consensus from the videos I watched.
