Recipe Notes
Spice Packet: Corned beef briskets usually come with the spice packet. If yours doesn't, you can buy the pickling spice separately. You'll need 1 ½ tablespoons pickling spice.
For especially thick (or thin) briskets, you may need to adjust the cooking time. In general, I'd recommend an extra 5 minutes for a brisket that's thicker than 1 ½ inches, and then another 5 minutes for every ½ inch beyond that.
Always slice your brisket against the grain, a.k.a. perpendicular to the parallel lines of muscle fiber that runs through the meat. The grain can run multiple directions in one brisket, so you may need to adjust how you're cutting.
