The Midnight cook instructs to flip the brisket over about halfway through the cook - is that necessary?? Seems like it would be better to leave the fat side up throuhout the entire cook.
Cook it fatside down for the entire cook. The fat will protect the meat from radiating heat from below. Fatcap is not the kind of fat that melts and 'bastes' the meat. When resting, rest fatside up.
