Recipe Note
Most butcher shops can get whole “packer trimmed” briskets for you, though it often requires ordering in advance. In certain parts of the country all you can find are the small “flat” cuts, often in the 4 to 6-pound range, and while these will suffice, a whole brisket cooks up much better.
A 4 to 6-pound “flat” cut will cook for approximately 8 to 10 hours; an 8 to 14-pound whole “packer trimmed” brisket will cook for approximately 14 to 18 hours
