I cooked my 3rd brisket this weekend. a friend purchased a 12lb'er from sam for $2.48/lb and asked me to cook it. I put it on the 22 kettle vs. the wsm given the size. I had a hard time getting the temps up to 350 or even 325 for that matter but part o fit was related to having one top lid vent plugged with foil/thermometer. Once i cracked the lid, the temp came up. At 2 hrs, tip was 171, foiled and cooked for another 2 hrs and internal temp at fat end reached 210. Then, another 30 min to firm up meat out of foil, so 4.5 hrs total. I hammered it pretty good for the 1st 2hrs w/ apple and hickory. It turned out fantastic. thanks for the HH recipe and tips on this site.
