JapanKatsuobushi Day
Katsuobushi are smoky, fermented, and dried bonito flakes that form the backbone of Japanese dashi. Blocks of skipjack tuna are repeatedly smoked, inoculated, and aged until rock-hard, then shaved into pale pink ribbons that dance in heat and dissolve into broth. A handful of flakes with kombu yields the clear, savory stock behind miso soup, simmered dishes, and countless sauces. Katsuobushi Day in late November plays on a phrase for “good flakes” and honors this cornerstone of Japanese flavor. The aroma of freshly shaved katsuobushi is one of the kitchen’s great invitations. Flakes also top okonomiyaki and takoyaki, waving in the steam like tiny flags. Though bags of pre-shaved flakes make dashi easy, traditional wooden shaving boxes still appear in serious home kitchens. On Katsuobushi Day, make a simple dashi with flakes and kombu, sip it plain, then turn it into miso soup or a simmered vegetable dish. Sprinkle flakes over hot rice or a savory pancake. Celebrating katsuobushi is celebrating the invisible savor that defines Japanese cooking.
