hi there guys, well most of the briskets that i can get here comes like this, seems that there is a large portion of fat that can weight about 1 pounds in a 11-12 pound brisket. After i remove it, the brisket looks more flat. Sometimes that part should have about an inch or less, with or without meat. Is not soft fat. If you pull enough hard you can actually remove it with your hands, sometimes with a help of a knife.
Here is some pics:
Tried to put some lines so you can recognize what im trying to explain.
