Dashi (出汁)

Step 1

Add the konbu to the water and soak for at least 3 hours. You can store this konbu dashi in a refrigerator for up to 3 days.

Step 2

Remove the konbu and bring the dashi to a boil (you can use the konbu for something else).

Step 3

Turn off the heat, and add the katsuobushi. Let this steep for 3-4 minutes.

Step 4

Strain the dashi and use it right away, or let it cool completely and store it in the refrigerator.
