Bonito Flakes (Katsuobushi) Calories

Bonito flakes move because rising steam and heat create small air currents that lift and curl the light shavings. The effect is especially visible on hot dishes such as okonomiyaki; the flakes are not alive.

Steep bonito flakes in hot water, then strain them out to make a simple dashi. For a more rounded Japanese-style stock, steep kombu in the water first and add the bonito flakes afterward.

For dashi, dried shiitake mushrooms can add savory depth, while dried small fish provide a more distinctly seafood-like alternative. Neither tastes exactly like bonito flakes, so the best substitute depends on whether you need umami, a fish flavor, or both.

Keep opened bonito flakes tightly sealed in a cool, dry place, away from moisture and strong odors. If the package calls for refrigeration, seal it well before chilling so condensation does not dampen the flakes.

Yes, bonito flakes are commonly sprinkled onto food without further cooking. Add them just before serving for a light texture, or steep them in hot water and strain them out when making broth.

Bonito flakes are usually made from skipjack tuna, Katsuwonus pelamis. The fish is dried and smoked before being shaved into thin flakes, so the name refers to the prepared ingredient rather than fresh bonito.

Traditional katsuobushi is made by simmering bonito, removing its bones, smoking it repeatedly, and drying it. Some varieties are also matured with mold before they are shaved, which develops their distinctive aroma and savory taste.

Bonito flakes taste savory, smoky, and deeply umami, with a light seafood character. Their flavor is concentrated, so they work well as a finishing sprinkle or as the base of a broth rather than as a large main ingredient.

No, bonito flakes do not need to be cooked before serving. They are often added directly to hot rice, noodles, or Japanese pancakes, while simmering or steeping them is useful when you want their flavor in a broth.
