Deep breath. Ohmmmm............ohmmmm.............ohmmmm.
You can either wrap in a disposable pan (easiest) or double wrap in HD aluminum foil. I prefer double wrapping. If you double wrap, it is better to have too much foil than not enough.
With a 5.75 lb brisket flat you won't need much liquid in the pan or foil, about a half cup is all. Personally, I heat the liquid in the microwave before adding it to the foil. Heating the cold liquid prevents it from cooling the meat.
With brisket, when I wrapped, I liked to add only beef broth. Stout beer goes well with beef brisket too.
Another trick is to skip the liquid and wrap with a full onion, sliced thin. You can put the onion on the bottom or top. I prefer the top. I usually do this with chuckies and brisket flats.
Enjoy the brisket!
