Don't mistakes these for wood shavings! Bonito flakes come from smoked and dried skipjack tuna -- the backbone of much Japanese cooking. It is used to make soup stock or add extra flavour. These large flakes have the pronounced fresh aroma and flavour of the sea. Although used primarily as a broth for miso soup or in Japanese sauces, Bonito Flakes can be used as a garnish on cold dressed tofu with ginger and green onions or combined with sesame seeds and sprinkled on cold dressed soba noodles.
