I'm relatively new to smoking but here is my situation. I started to smoke a 6 lb brisket at 185 degrees at 11 pm last night. I woke up at 630 am wrapped it in butcher's paper and then turned it up to 225 degrees. Everything was fine until I left the house for an hour and a half and came back to my smoker which was off due to the pellets being jammed. I cleaned it all out and fired it back up. When I put the probe back in, the brisket was at 139 degrees. Is this still ok to continue to cook, or should I toss it? I was really looking forward to eating this until everything happened.
