How Tokyo's teppan and charcoal rooms treat very marbled beef: cut small, seared fast and hard so the fat melts without the meat overcooking, cut into bite-size pieces, and eaten with the simplest things: salt, fresh wasabi, garlic chips and a little ponzu.
8 to 12 oz (225 to 340 g) Japanese or high-marbled wagyu sirloin or rib eye, about 1 inch (2.5 cm) thick
Flaky sea salt
4 garlic cloves, thinly and evenly sliced
3 tbsp neutral oil
Fresh wasabi (or good tube wasabi)
For the ponzu: 3 tbsp soy sauce, 2 tbsp fresh yuzu or lemon juice, 1 tbsp mirin
Optional: a handful of bean sprouts or shishito peppers, a bowl of steamed rice
How to make it
Take the beef out 20 minutes before cooking. Pat it very dry. Trim any thick outer fat and keep a small piece to grease the pan.
Mix the ponzu. Put the garlic and the oil in a cold small pan, set it over medium-low heat and cook 4 to 6 minutes, swirling, until the slices are pale gold. Lift them onto paper; they crisp as they cool. Keep the garlic oil.
Heat a heavy cast-iron pan or griddle over high heat for 4 minutes. Rub it with the piece of beef fat.
Salt the steak lightly and lay it in. Sear 60 to 90 seconds until a deep crust forms, turn and sear 60 to 90 seconds more, and sear the edges for a few seconds each. Wagyu cooks fast: you want 125°F (52°C) inside at most; the fat should be melting, not rendered out.
Rest it 2 minutes, then cut it into 3/4-inch (2 cm) cubes or strips.
In the same pan, toss the bean sprouts or shishitos in the beef fat for 1 minute.
Plate the beef with a small mound of flaky salt, a dab of wasabi, the garlic chips and a little dish of ponzu. Each bite gets only one: salt, wasabi or ponzu. Rice on the side.
Tips
Portions are small on purpose: 3 to 4 oz (100 g) per person of very marbled beef is plenty.
A Korean table does it differently: thin slices on a grill at the table, wrapped in lettuce with ssamjang.
