Do I need to trim the fat on a brisket before cooking?
If the brisket is being cooked in a smoker or grill, it is a good idea to get the bark from the rub directly on the meat by trimming the fat before cooking. In this closed-baked method, it is not needed. It is very easy to scrape the fat off immediately after cooking when still hot. It is also the ideal time to separate the muscles of your cooked whole or flat brisket.
