Surugaya Hana Katsuo Bonito Shavings are a high-quality Japanese ingredient made from dried and smoked bonito fish. They are thinly shaved into delicate flakes and are a staple in Japanese cuisine. These flakes are commonly used to create dashi (a foundational soup stock), garnish dishes like takoyaki, okonomiyaki, and cold tofu, or enhance the flavor of soups, stews, and sauces.
