And here's the final results: I didn’t want to do a whole 15-lb brisket because that would mean me starting it at midnight, going to bed and worrying about monitoring the temperature overnight (because something can ALWAYS go wrong if you are not watching it). With the 6lb flat, it was only the lean portion of the brisket, but I started it about 10AM and took it off at 6:30, rested it for an hour, and then sliced it. (Photos). It actually turned out pretty well: nicely moist, not dried out, and good flavor. I had rubbed it with Lawry’s Seasoning Salt and coarse ground pepper. The bark did not turn out quite as I had hoped- I think it was the Lawry’s- will experiment next time with just plain old coarse sea salt and pepper. I didn’t have any post oak and since I wanted a stronger smoke, so I used mesquite, and that part turned out quite well. The sliced meat looks a little grayish in this photo, and I attribute that to this particular flat- it was choice grade, as Costco didn’t have any prime out in the cooler. In any case, it was perfectly tender and moist- I took it off to rest it (1 hour, wrapped and tented) when the temp probe showed 200*, and I think allowing for measurement error, it was just right. We sliced it like a London Broil and ate it with homemade mashed potatoes and vegetables- yum.
