Go by temp not by time...... did you pan and foil at 160 with juices...... I take em to 196 then foil and wrap in a towel for an hrI have myself a bit of a problem. My brisket is 12 pounds and should take 18 hours at 225. Internal temp is at 188 12 hours. Do I trust the thermometer or leave it in for the 18 hours?
