Dashi stock varies from region to region and from housewife to housewife. This page explains how to make the three basic types of dashi: katsuo dashi, niboshi dashi and mixed dashi, which combines kombu and bonito flakes.
Katsuo Dashi
Katsuo (bonito) dashi has a distinct rich taste and is not hidden by seasoning.
It is also used for noodle soups.
Ingredients of Katsuo Dashi
Water 800cc
Bonito flakes A handful 30g
Directions
Do not keep boiling the water after adding the bonito flakes.
Do not squeeze dashi stock strongly from the strained bonito flakes.
How to Choose Bonito Flakes
Bonito flakes (kezuri-bushi) best for making miso soup at home are large and thin flakes. Blackish bonito flakes containing dark flesh give a rich dashi taste. Thick bonito flakes and mackerel flakes also give rich dashi tastes.
Niboshi Dashi
(Iriko Dashi)
Niboshi is dried sardine, and its dashi stock is widely used in the Kansai area.
Niboshi dashi stock is rich in both taste and flavor.
Ingredients of Niboshi Dashi
Water 800cc
Niboshi (Iriko, or dried small sardines) 32g (8 ~ 12 dried sardines)
Directions
The heads and guts cause a smell. Remove them thoroughly.
Skim the scum thoroughly.
How to Choose Niboshi
Choose niboshi which are well dried and have their backs bent toward the bellies. They are fresh niboshi.
If their bellies are bent toward the backs or if they have broken backs or hollowed bellies, they are not fresh niboshi. Avoid such niboshi.
Mixed Dashi
Mixed dashi is a dashi stock combining katsuo (bonito) and kombu seaweed.
It has a delicate and mild taste.
Ingredients of Mixed Dashi
Water 800cc
Kombu 16g (2 square pieces of 8-cm)
Bonito flakes 25g
Directions
Avoid boiling the kombu.
Do not squeeze dashi stock strongly from the strained bonito flakes.
How to Choose Kombu
For miso soup, choose kombu which are well dried and thick and has a good flavor.
Kombu is graded strictly in Japan according to their sea areas (areas of production).
