Katsuo (bonito or skipjack tuna in English) is a medium-sized fish related to tuna and mackerel. The meat of the Katsuo looks similar and has a similar texture to tuna meat. Katsuo is commonly used in Japanese cooking, but that is a subject for another blog. “Tataki” is a cooking method that originated in the Kochi area. The food is seared over an open flame or in a frying pan, leaving the internal part of the fish uncooked. It is thought that Sakamoto Ryoma, a famous samurai born in Kochi who lived at the end of the Edo Period, copied this style of cooking from Europeans in Nagasaki. Traditionally in Kochi, Katsuo Tataki is seared over a rice straw fire.
Katsuo Tataki is one of the local specialties of Kochi, and its most famous dish. Searing the Katsuo filets over the open rice straw fire gives the fish a slight smoky flavor. After the outer layer is seared, the filet is often placed in ice water to stop further cooking, leaving the internal part of the fish uncooked. The filets are then sliced, sprinkled with salt, and served with garlic, onion and ginger garnish. It is also commonly covered in a dressing of soy sauce and citrus.
