Cooking 8.5 lb pork butt overnight ~225 dome. Put it on a 6pm, checked at 2am and was still maintaining temp. Check at 8am (6hrs later) and dome was at 150. Butt temp was about 155ish, but felt kind of tough (in some places - not all) when I inserted thermometer. The juices definitely didn't come running out like they do sometimes hen inserting the thermo.
Is this butt doomed, or there still a chance at salvaging some decent pulled pork?
