Getting so many great tips from everyone it almost makes me want to try another brisket soon to try all these tips out. I've almost been tempted to do that millerbuilds separate the flat and the point so that I don't overcook the point while undercooking the flat. But might try to round off my brisket next time and maybe grind what I cut off have been using some ground brisket in different recipes and it's so good and different.
The point shouldn't be a problem.
I believe you may have a tougher time if doing just the Flat alone should you separate them. The fat from the point really helps the Flat cook up and not dry out.
If I were to cook a Flat seperate or alone I feel I would be forced to wrap to keep it from drying out. In my MES I never have to wrap a whole packer brisket.
Just some info to consider.
Also while you are figuring out what to do I would try and keep it as simple as possible and not make too many adjustments.
A cheaper way to practice is to do a pork butt, BUT applying some of the things you plan to do with your brisket like tenderness checking, wrap vs no wrap, changes in seaosning, etc. etc.
If you change a few things and perfect some techniques on a pork butt (tenderness checking and probe placement) chances are you will have no issue with those things on a brisket. THEN you can work on brisket specific stuff like Flat trimming or attempting a truss.
I personally LOVE ground brisket for burgers so when you mentioned that I was thinking "mmmm hell yeah!" hahaha.
Often simplicity is the best approach and practice makes perfect :D
