Katsuodashi

Katsuo dashi is a broth in Japanese cuisine made by simmering dried bonito flakes (katsuobushi). It forms the base for a wide range of dishes, including soups such as miso soup and various sauces. Making katsuo dashi is a careful process in which the bonito flakes are briefly brought to a boil and then skimmed off to produce a clear, aromatic stock.

The etymological composition of the term combines the kanji 鰹 (*katsuo*), meaning “bonito,” and 出汁 (*dashi*), meaning “broth” or “stock.” Historically, katsuo dashi has played a central role in the development of Japanese cuisine and reflects the high regard for umami-rich ingredients.

The use of katsuo dashi makes it possible to achieve the characteristically deep flavor and umami notes valued in many traditional Japanese dishes. It is not only a culinary foundation but also a cultural element that illustrates the connection between Japanese food culture and its natural resources.
