Seared Bonito (鰹のたたき, Katsuo no Tataki)

Katsuo is a fish with two good seasons. In spring, hatsu-gatsuo runs lean and clean as it moves north; in autumn, modori-gatsuo returns richer, carrying fat from cold water. Either can make tataki, but only if it is glistening fresh and fit to eat raw. Sourcing first, always. The flame is there to honor good fish, not rescue tired fish.

People make warayaki, straw searing, sound like a ceremony guarded by smoke and brave eyebrows. It isn't. The first secret is violence kept brief: a fierce straw flame, or the hottest grill you can manage, catches the skin and warms the surface before the center has time to cook. Straw burns fast and clean, leaving a grassy sweetness. At home, a charcoal grill or broiler is a sensible stand-in, but the rule remains the same: mark the outside, protect the cool red heart.

Then let the knife do the quiet work. Slice thick, not thin, because tataki needs the contrast of singed edge and raw center in one bite. Garlic, ginger, scallion, myōga, and ponzu are not a mask; they sharpen the fish and then get out of the way. On a Japanese table this sits as the main seafood dish beside rice, soup, and a small simmered thing. Leave it room, and serve it while the cut faces still shine.
