Trim the brisket the night before your cook. Place it fat-side up on your cutting board and use a sharp boning knife to trim the hard fat cap down to a uniform 1/4-inch thickness. Remove any hard chunks of fat that will not render during the cook, particularly the thick deposit between the flat and the point. Flip it over and trim away any silver skin or thin, papery fat on the meat side. Your goal is a brisket that looks aerodynamic and uniform so heat wraps around it evenly. A well-trimmed brisket promotes better bark formation and more even cooking from edge to edge.

Apply your rub after trimming. If using a binder, coat the entire brisket in a thin layer of yellow mustard or beef tallow to help the seasoning stick. Mix your kosher salt and coarse 16-mesh black pepper in a 50/50 ratio by volume. This is the classic Central Texas SPG rub and it is all you need. Season every surface generously, pressing the rub into the meat. You want a visible crust of seasoning covering every inch. Wrap the brisket in plastic wrap or place it uncovered on a rack in the refrigerator overnight for a minimum of 8 hours and up to 24 hours. The dry brine draws moisture to the surface, the salt dissolves, and then gets reabsorbed, seasoning the meat deep below the surface.

Fire up your smoker 60 to 90 minutes before the brisket goes on. Your target pit temperature is 225 to 250 degrees Fahrenheit. If you are running an offset smoker, build a fire in the firebox with seasoned hardwood and let it burn down to a clean, thin blue smoke. Avoid thick white billowy smoke, which is a sign of incomplete combustion and will leave a bitter, acrid flavor on the meat. Add your smoking wood chunks or logs and dial in your temperature using your intake and exhaust vents. Stabilize your pit for at least 30 minutes before loading the brisket.

Place the brisket fat-side up on the smoker grate, positioning it in the center of the cooking chamber away from direct heat. If running an offset, orient the flat end toward the firebox since it is the thinner, leaner muscle that dries out faster, and the thicker point can handle more direct radiant heat. Insert your leave-in probe thermometer into the thickest part of the flat, being careful to keep the probe away from any fat seams. Close the lid and resist the urge to open it for the first 3 hours. Let the smoke do its work.

Every 60 to 90 minutes during the first 6 hours, open the smoker and give the brisket a spritz with your apple cider vinegar and water mixture. This keeps the exterior moist, encourages smoke adhesion, and helps build that deep mahogany bark color. Check your pit temp each time you open the lid and adjust your vents accordingly to maintain that 225 to 250 degree range. Add wood as needed to keep your thin blue smoke rolling. During this phase you will notice the brisket sweating, the surface beginning to darken, and the fat starting to glisten and render.

Expect the stall. Around 150 to 165 degrees Fahrenheit internal temp, your brisket will plateau and the temperature will stop rising for anywhere between 2 and 6 hours. This is completely normal and happens because moisture evaporating from the surface of the meat cools it at the same rate your smoker is heating it. Do not panic and do not crank up your heat. The stall is where that incredible bark is being built. You have two choices: power through it and wait it out, or wrap the brisket to push past the stall faster.

Wrap the brisket when the bark is fully set, typically around 165 to 170 degrees Fahrenheit internal temp. The bark should feel firm, dry, and almost leathery when you press it. For maximum bark integrity, use pink unwaxed butcher paper. Lay out two overlapping sheets of butcher paper, place the brisket fat-side down in the center, and wrap it tightly like a burrito, folding the sides in first and then rolling it up. If you prefer a softer, more braised result, use two layers of heavy duty aluminum foil and add a splash of beef tallow or a couple pats of butter before sealing. Return the wrapped brisket to the smoker fat-side down.

Continue cooking the wrapped brisket until the internal temp of the flat reaches 195 to 205 degrees Fahrenheit. Begin probing at 195 degrees. Insert your thermometer probe into multiple spots across the flat and into the point. What you are looking for is zero resistance, the probe sliding in and out like it is going into warm butter or room temperature peanut butter. The point will almost always be done before the flat. Do not pull the brisket based solely on temperature. Probe feel is the final authority. A perfectly done brisket should wiggle like jello when you shake the foil-wrapped package.

Rest the meat. This step is non-negotiable and skipping it is the most common mistake backyard pitmasters make. When you pull the brisket off the smoker, do not slice it. Place the wrapped brisket into a dry empty cooler lined with towels and close the lid. Rest it for a minimum of 1 hour and ideally 2 to 4 hours. During this rest period the carryover cooking finishes the job, the muscle fibers relax, and the juices redistribute throughout the entire brisket. Slice a brisket that has rested properly and the juice runs out onto the cutting board. Slice it too early and all of that juice ends up in a puddle while your meat dries out.

Slice and serve. Unwrap your rested brisket and pour any accumulated juices into a small bowl to drizzle over the slices. Place the brisket on your cutting board with the flat and point visible. Separate the point from the flat by cutting through the fat seam between them. Slice the flat against the grain into pencil-thick slices, about 1/4-inch each. The point has grain running in a different direction, so rotate it 90 degrees and slice it against its grain as well, or cube it up for burnt ends. Lay your slices out on butcher paper or a wooden serving board, drizzle with those reserved juices, and serve immediately.
