Katsuo, or skipjack tuna or bonito, is a fish well-loved by the locals. For this dish, the katsuo is seared on the outside while the inside remains raw, like sashimi. In Kochi, the katsuo is grilled over high flames created using the rice straws, thus drawing out the rich aroma and flavour of the fish. The katsuo is then thickly sliced to ensure each bite is highly satisfying. Ponzu, Japanese citrus fruit yuzu mixed with soy sauce, is usually served with this dish. Other common condiments include salt, sliced raw garlic and ginger, onions, wasabi, perilla leaves, and myoga ginger.
