I put two 7 lb butts on the egg at 4PM keeping the temp between 225 and 250. It's only been 6 hours and the probe is reading 172! What happened to the 20 hour cook I'm supposed to have? Dinner isnt until 2:00 tomorrow afternoon. I know this cook usally has a "stall" but it had better be a helluva stall to prevent this meat turning to jerk!
