My Brisket Ive been smoking has gone crazy. I am doing jeffs method and had it on the smoke for 5 hours and took it off at 150 i put in a foil pan and covered it with foil. The Temp shot up to 185 in a hour in a half. I took it out of the pan and put it back on the grate and the temp has gone down to 165 and hasnt moved for a hour. My smokers has been at 250 the entire day. Any suggestions to not have this thing all dried up.
