How to Make a Basic Dashi
Dashi is the clear seafood broth that is the foundation for many Japanese soups, sauces, dips, and marinades. To make one quart of dashi, you will need:
1 quart of water
1 4" piece of dried konbu (dried sea kelp)
1 cup of katsuo (dried bonito shavings)
Rinse or wipe the dusty coating from the surface of the konbu, place in a pot with one quart of water and cook over high heat. When the water comes to a boil remove and discard the konbu.
Add the katsuo flakes and bring to a boil again. Remove the pan from the heat and allow it to cool. Strain the liquid into a separate container and discard the katsuo.
The remaining liquid is called dashi and can be used as a base to make a wide variety of Japanese soups and sauces.
