i've been babysitting this 4lbs. brisket flat for 6 hrs. now. I have a baby char-grill offset temp has been hanging around 200 deg. to 275 deg. hadd to leave for about an hour and had the wife watch( or she was suppose to be watching) to get a thermometer, when i got back smoker temp was about 100(don't know what happened) internal temp of brisket is at 140 deg. and will not go up. Any suggestions or should i just try to save it in the oven? thanks guys
