I started a 12# brisket (had to cut it in half to fit it - the flat on one rack and the point on another) last night at 9:00 in my vertical propane smoker. By this morning, it had reached 142 IT in a 225 smoke. Here I sit at 4:00 this afternoon, and it's at 156 IT. I wrapped it when it hit 160 (at 2:00 pm) to speed it up, but it's only dropped since then. What gives? I've tried resetting my maverick et-732, but it still reads the same. At this rate it'll end up being tomorrow before it's ready.
