I am cooking one as I type (my first attempt though)
200 degrees, placed on the top rack, water pan under the flat side of the brisket (not sure if this matters), crumpled up aluminum foil under brisket so juice doesn't collect in the middle. Seasoned with Killer Hogs TX rub (basically Salt Pepper Garlic). Gourmet blend weber pellets. Injected in 1" squares, about a teaspoon, with Butchers Prime Brisket Injection mixed with water.
I put it on last night for 8.5 hours, didn't spray or anything because I went to sleep.
Temp was 141deg in the thickest part of the flat when I took it off
, but the bark was definitely set, but also it felt maybe a touch too dry? Definitely felt nice though. I poured some beef broth over the top of the brisket in very small amounts to rehydrate the bark a tad then wow it looks amazing. I wrapped it in butcher paper and put it in the oven that was preheated to 275 (middle rack).
Total cook time so far has been 12.5 hours. I plan on poking it when it gets to 200ish, and I just left the stall.
I originally planned for it to be a 17h cook with a 2h rest, and it looks like I'm right on track!
Post cook I am going to do a few burnt ends (using Head Country BBQ, butter, brown sugar, and the Au Jus from the brisket) and cook to thicken it up.
I am very hopeful as everything looks very promising so far.
