Sho quickly sears it directly on hot coals, wipes away any coal residue, and serves it extra-rare. Here, we use tenderloin— also excellent—and a superhot pan. If you prefer your meat more well-done, sear the steak a few extra minutes on each side.

1/8cupshaved red onion,for garnish (optional)

Instructions
Generously season the beef with salt and pepper. Heat a cast-iron or heavy stainless steel pan or grill pan over high heat. Sear each side of the beef just long enough to brown but not cook through, about 2 minutes per side. Set aside to cool.
In a small bowl, mix together the tamari, vinegar, lemon juice, garlic, sesame oil, and a few grindings of pepper. Set the sauce aside.
With a very sharp knife, slice the steak into very thin pieces and arrange them on a platter. Drizzle with the sauce, garnish with the sesame seeds, mizuna, red onion, and radish sprouts, and serve.
