鰹節（かつおぶし、katsuobushi）
- bonito flakes

鰹節 is a fundamental ingredient in Japanese cuisine, consisting of dried, fermented, and smoked skipjack tuna. The process creates a hard, flavorful block that is shaved into thin flakes before use. These flakes, called 花かつお (hana katsuo), are used to make dashi, a crucial soup stock that forms the base of many Japanese dishes. The taste profile is umami-rich, savory, and slightly smoky. This is because 鰹節 is the result of a very long and specific manufacturing process.

⚫︎鰹節で出汁をとる。 Translation: I make dashi with katsuobushi. ⚫︎味噌汁に鰹節を少し加えた。 Translation: I added a little katsuobushi to the miso soup. ⚫︎お好み焼きには鰹節が欠かせない。 Translation: Katsuobushi is indispensable for okonomiyaki.

This word is used to refer to both the block of dried tuna and the flakes produced from it. When speaking about using it in cooking, you would typically use it in the form of the shaved flakes or when talking about the preparation. It is commonly used in recipes, cooking instructions, and descriptions of Japanese cuisine.

⚫︎The word is primarily written in kanji as 鰹節. ⚫︎The reading is かつおぶし in hiragana. ⚫︎There is no variation in the okurigana.

⚫︎花かつお (hana katsuo): The shaved katsuobushi flakes. ⚫︎Dried tuna flakes (general descriptive term).

There are no direct antonyms, but you could consider "fresh tuna" or "unprocessed tuna" as a contrast, though not a direct opposite.
