Katsuo no tataki
Kochi, on the Pacific coast of Shikoku, is Japan's bonito town. At Hirome Market in the city centre, cooks sear whole loins over roaring straw fires and slice them to order, served thick with garlic slices, onion and ponzu or just a pinch of salt. Bonito has two seasons there: the leaner first catch of spring and the fattier fish returning south in autumn. At home a very hot dry pan, or a blowtorch, gives the same charred skin around a cool red centre. Use very fresh, sushi-grade fish from a trusted fishmonger; not for pregnant women, young children or anyone with a weakened immune system. Chef's tip: slice it thick, about 1 cm, as they do in Kochi; thin slices lose the contrast between the smoky crust and the soft middle.
