Due to scheduling, I had to start the butt early. I anticipate it will sit for maybe ~8 hours before we eat. We'll have to heat it in the oven. Should I just leave it in it's foil and throw it in the oven? If so, what temp would you guys warm it at and for how long? Also, I can use my instant probe. What internal temp should I warm the butt to for serving? Thanks guys!
