Packer Brisket

Place the cold 3.6kg whole packer brisket on a large stable cutting board. Use a sharp boning knife to trim hard, waxy fat from the flat end to leave a uniform 6mm (1/4 inch) thick fat cap, remove the tough silver skin from the exposed meat side, and trim loose, dangling fat pieces from the point end to create a smooth, even surface. Pat the entire brisket completely dry with paper towels after trimming, which takes approximately 15 minutes total.

Stir 45g kosher salt, 24g coarse black pepper, 9g garlic powder, 7g onion powder, and 7g smoked paprika in a small mixing bowl to combine evenly. Coat the entire surface of the trimmed brisket with 30ml yellow mustard as a flavor-neutral binding agent, then sprinkle the dry rub evenly over all sides of the brisket, pressing gently to help the seasoning adhere so every surface has a thin, uniform coating. Let the rubbed brisket rest at room temperature for 45 minutes while you preheat your smoker.

Preheat your offset or pellet smoker to 107°C (225°F) set to indirect heat. Add 500g of oak wood chunks to the fire box once the smoker reaches target temperature, waiting until thin, wispy pale blue smoke flows from the exhaust (avoid thick, billowing white smoke, which creates bitter, ashy flavor on the meat). Place a metal water pan filled with 2L of warm tap water on the indirect heat side of the smoker to maintain a moist cooking environment.

Place the seasoned brisket on the indirect heat side of the smoker grate, fat side up. Close the smoker lid and maintain a consistent internal chamber temperature of 107–121°C (225–250°F) for 6–7 hours, adding 1–2 small oak wood chunks every 2 hours to maintain steady, light smoke, until the internal temperature of the brisket's thickest point reaches 71°C (160°F), the temperature known as the 'stall' where evaporation cools the meat and stops temperature rise for several hours. Avoid opening the smoker lid unnecessarily during this period to prevent heat loss.

Carefully remove the brisket from the smoker once it hits 71°C (160°F) and has a deep mahogany bark, and wrap it tightly in the 1-meter sheet of pink butcher paper, folding the edges over twice to seal in steam without making the wrapping too loose. Return the wrapped brisket to the smoker, maintaining the same 107–121°C (225–250°F) indirect heat, and cook for an additional 4–5 hours until the brisket's internal temperature reaches 93–96°C (200–205°F), and a meat probe slides into the point end with zero resistance, like pushing a knife into soft room-temperature butter.

Remove the wrapped brisket from the smoker once it passes the soft butter probe test and reaches target internal temperature. Wrap the butcher paper-wrapped brisket in an additional layer of heavy-duty aluminum foil to hold heat, then place it in an insulated cooler (no ice required) with a folded kitchen towel tucked around it to retain warmth. Let the brisket rest for 1 full hour, allowing muscle fibers to relax and reabsorb juices to prevent runoff when slicing; do not skip this critical step.

After the 1-hour rest period, unwrap the brisket, pouring any collected rendered juices into a small bowl to reserve for serving. Separate the point and flat muscle sections, noting that the grain runs in different directions on each cut. Slice the flat section across the grain into uniform 6mm (1/4 inch) thick slices, and either pull the tender point section into burnt end chunks or slice it across the grain as well. Drizzle reserved juices over the sliced meat and serve immediately.
