Did my first high temp brisket Sunday. A co-worker asked me if I would do a brisket for him, and he offered to pay, so I said sure. Been wanting to try one at high temp for a while. I told him that it would be my first time at high temp, and also told him if it didn't turn out good he wouldn't have to pay me. He agreed. I bought a 11# packer from Wally World, and used the rub I had left over from my last pork butt smoke. Fired up the WSM, put on the meat, and left all the vents wide open for the entire smoke. Temps eventually came up to 325. Took about an hour. Cracked the lid, temps rose to around 400. Pulled the brisket when the internal reached 160. That took about 2 hrs. Pulled it, seperated it from the point, doulble foiled and back on the smoker with no temp probe. At about the 3.5 hr mark started checking for tenderness with the meat probe. Not quite there yet. Right at the 4 hr mark it was close enough. Pulled it, put it in an aluminium pan and tightly foiled it closed. The carry over cook in the foil pan should have taken it the rest of the way to tender. Took it to work, without a peek or sample. I was nervous on how it would turn out. Towards the end of the day he couldn't resist. He sliced a few pieces of and it by far is the best brisket I have ever done. Nice smoke ring, and very juicy. This will be my method from now on. Next one I do I will take pics.
