So...I bought a 16lb prime brisket. I started somking it and it has been on my smoker for 20 hours. I hit the stall around 160. It came out of that stall and got to about 190. Now it stalled at about 190 for 4 hours. Has anybody else had this happen? I know i need to wait for it to be like butter and the probe needs to go in easy...but I've never had this happen and it seems odd...still waiting for it to get to 198.
