Bonito flakes

Bonito flakes (Japanese: katsuobushi) are thinly shaved, fermented, and dried slices of skipjack tuna (Katsuwonus pelamis). One of the most essential ingredients in Japanese cuisine, together with kombu, they form dashi, the classic Japanese broth. They have a characteristic amber-pink color, smoky-fishy aroma, and a distinctive umami flavor. Used not only for dashi but also as a topping for tofu (hiyayakko), okonomiyaki, takoyaki, and onigiri. The flakes appear to "dance" under hot steam.
