How many pounds of brisket for 700 people?

To serve 700 people, you'll typically need about 0.5 pounds of cooked brisket per person, which accounts for shrinkage during cooking. This means you'll require approximately 350 pounds of cooked brisket. Since brisket loses about 30% of its weight during cooking, you'll need about 500 pounds of raw brisket to yield the desired amount.
