How To Cook Dried Bonito Flakes?

Bonito fish is used in making these flakes and is grated well. Here is a step-by-step guide to cooking this item:

  • Cutting

The bonito fish is cut into 3 parts (the right side, the left side, and the spine portion). Likewise, four Fushi (dried bonito pieces) are made by a single fish. The top two fillets are known as male fillets while the bottom two are known as female fillets.

  • Placing in Basket (kagodate)

A boiling basket known as ‘Nikago’ is used to keep the bonito fish in an organized manner. Similarly, care is taken while putting the fish in the basket in such a way that all pieces are boiled properly.

  • Boiling Procedure

The optimum temperature for boiling the bonito is 75-98 degrees centigrade. The time required is 1.5 to 2.5 hours which may vary with fish.

  • Separating Bones

Small-sized bones are later on removed with the help of tweezers to clean the fish. It requires much attention and care.

  • Smoking the bonito

After removing the skin and bones, the bonito is smoked by cherry blossom and oak. This process is repeated multiple times until the desired result is obtained.

  • Surface Shaving

The tar with some fat is then shaved off from the surface of the fish to get a clean bonito flake with some other little procedures.

  • Drying

Nothing is better than the sunlight for drying purposes, hence the bonito is kept under the sun for 2 to 3 days. It is a very long process and after applying mold on the surface, the whole process is repeated multiple times. The bonito is reduced in weight and it takes almost 6 months to 2 years to do so.

  • Shaving

Specially designed shavers are used to get the classically shaped bonito flakes. If the shaver is not good, it may turn the dried bonito into powder.

Quick Dashi
