These flakes from Matoba Suisan are made from katsuobushi known as Arabushi, which is skipjack tuna that has been poached and smoked. The fact that each step is done by hand demonstrates Matoba-san’s dedication to artisanal, traditional production methods. They are a wonderful addition to any dish as a topping. You can add a smoky, slightly salty, umami rich savoriness by simply sprinkling on top of dishes like Takoyaki, Agedashi tofu, etc. Store at room temperature away from direct sunlight. Keep refrigerated after opening. About the producer: Located in the port town of Makurazaki in far southern Kyushu, Matoba Suisan crafts katsuobushi using traditional methods.
