Dried bonito (Katsuobushi – かつお節) is a Japanese preserved food made by boiling the meat of bonito and then drying it.
Cut off the head, fins, and part of the abdomen from the fish, grate it into three or more pieces. Then, shape it into a boat shape called “fushi” before processing it.
The ones you can buy at Asian and Japanese supermarkets overseas are called “kezuri-bushi,” which are boat-shaped dried bonito shaved into very thin slices. Nowadays, shaved dried bonito is the standard, but in the past, hard dried bonito flakes were shaved with a wooden box shaver. People used to shave off chunks of dried bonito right before eating. The aroma is far better this way, so some people still choose this method.
