In a large bowl, whisk together the vital wheat gluten, nutritional yeast, smoked paprika, garlic powder, onion powder, black pepper, and fine sea salt until completely uniform. Make a well in the center.
3 tbsp nutritional yeast, 1 tsp smoked paprika, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp fine black pepper, 1/2 tsp fine sea salt
In a separate bowl, whisk together the beet juice, soy sauce, white miso paste, tomato paste, apple cider vinegar, and liquid smoke (if using) until the miso is fully dissolved. Pour the wet mixture into the dry ingredients all at once.
3/4 cup fresh-pressed or cold-pressed beet juice, 3 tbsp soy sauce or tamari, 2 tbsp white (shiro) miso paste, 1 tbsp tomato paste, 1 tbsp apple cider vinegar, 1 tsp liquid smoke
Mix immediately with a fork or dough hook until the dough comes together into a shaggy mass — about 60 seconds. Then knead by hand or on the stand mixer at medium speed for 3–4 minutes until the dough is cohesive and slightly elastic. Do not over-knead at this stage — you want the gluten network initiated but not fully developed, so the subsequent lamination folds can direct its orientation.
Lamination — the critical step: Turn the dough out onto a clean, unfloured work surface. Stretch it into a rough rectangle approximately 10 x 7 inches. Fold the far third over the center third, then fold the near third over that (like a letter fold). Rotate 90 degrees and repeat. Do this fold-and-rotate cycle 8 to 10 times in the same primary direction, stretching the dough firmly before each fold. You are physically aligning the glutenin and gliadin chains into parallel arrays — this is your fiber direction. Mark the final orientation with a light score or a small notch on one end so you remember it for slicing later. Shape the laminated slab into a rough oval or rectangular block about 8 x 5 x 2 inches thick.
Wrap the slab loosely in foil or parchment, leaving a small vent gap. Place in your steamer over vigorously boiling water. Steam for 50–60 minutes, flipping once at the 30-minute mark. The slab will firm considerably, develop a slightly tacky exterior, and deepen in color from the betacyanin. Remove and unwrap carefully — it will be hot.
Allow the steamed slab to cool to room temperature on a wire rack for 30 minutes, then refrigerate uncovered for at least 12 hours and up to 24 hours. The gluten network continues to cross-link during this cold rest, and surface moisture equalizes — both are essential for bark formation in the smoker.
