A four-to-five-pound brisket flat cooked covered with broth and a dry spice rub, rested and sliced across the grain.
Five-hour cooking allowance for a four-to-five-pound brisket flat; start checks at three hours and extend as needed. Covered from the start, with one cup broth. Whole-beef minimum 145°F/three-minute rest is only the safety minimum, not this recipe’s tenderness endpoint. Rest thirty minutes before slicing.
