“Mummy, look! The Katsuo-bushi is dancing on top of the rice.” June would always say whenever I serve her rice with Katsuo-bushi. What is Katsuo-Bushi? Katsuo-bushi かつお節, also being known as Bonito flakes is a smoked fermented fillet of skipjack tuna. It is an essential ingredient widely used in Japanese cuisine to enhance the umami taste of Kombu 昆布 – hence both of them are often being paired up together to make Japanese Dashi. However, Katsuo-bushi alone can produce flavourful dashi as well.
