I have done several butts but never injected one. Wanted to experiment but before I go down that road wanted to know how it affects cook time.
For instance, if I inject and rub the butt the night before, put it in the fridge overnight, take it out before smoking and bring to room temp before putting on smoker. Will the cook time be significantly longer because I have injected 16-24 ounces of fluid into the meat? or is it easier to smoke, foil and add the vinegar/apple cider/brandy concoction after the meat has been shredded?
