My first brisket is done and dusted!
Overall: not bad. A little overcooked, but the point had a good texture and was still juicy. The lean was too dry but still tasted good.
I cooked it overnight for 8hrs, with briquettes and oak/cherry chunks. Weirdly, the smoker struggled to get over 200F, but when I checked this morning, the brisket's internal temp was 166F, so fresh load of charcoal, and cooked for another 3hrs.
Took it off at 205F, then wrapped in foil and placed in coolbox for a couple of hours. I suspect I should have let it cool on the worktop for 20-30 mins first - another lesson learned!
I've cut the end of the point off and will make burnt ends later in the week, and I still have a huge slab of meat left, which I'll probably freeze.
Also, the brisket was just over 7kg, and in all honesty was too big for my ProQ Frontier - I had to prop it up a bit, and really cram it to make it fit. Will go for a 5kg brisket next time.
Always knew that my first brisket would be a steep learning curve, and so it proved. And even though it wasn't brilliant, it was still very tasty!
