What are bonito flakes?
Bonito flakes, or katsuobushi, are tissue-paper thin fish shavings with an intense umami flavour. Bonito flakes come from a tuna-like fish which is dried, fermented and then smoked. Bonito flakes are used alongside dried kelp to create the base of Japanese dashi stock.
How to cook with bonito flakes?
The most common use for bonito flakes is for making dashi, a stock used in Japanese cuisine which forms the base of miso soups and clear broths. Dashi is also mixed with flour to make the batter for Japanese okonomiyaki.
With their wafer-thin texture, bonito flakes make a great garnish, offering a pungent flavour and subtle appearance. Use them to garnish cucumber salads, fried tofu, somen noodles, or gently heat with soy sauce, sesame seeds and a touch of honey to make okaka - a popular Japanese seasoning for onigiri rice balls.

Frequently Asked Questions

Do bonito flakes taste fishy?
Yes, bonito flakes do taste fishy. Bonito flakes are a form of fermented and dried tuna which gives the flakes a pungent flavour. The smoking process gives bonito flakes an umami depth, too.
Can you eat bonito flakes out of the bag?
Technically speaking, you can eat bonito flakes out of the bag, however you’ll be met with a very strong fish flavour and flaky texture. Rather than snacking on bonito flakes, we suggest using them to garnish noodle salads, smoked tofu or rice balls.
