I just got home with a 7.5lb butt. I went back and reread the thread G posted a few days ago and got a lot of good info. However, I still have a few questions. I'm not going to cook it until tomorrow so is there anything I need to do to prep it? Should I let it marinade in pineapple juice overnight? Should I inject it with Cajun Injector Creole Butter? I've had the Creole Butter opened for six months or so, is it still good? Your input is appreciated.
