Easy Dashi

Directions

1. 1
   In a large saucepan, combine the kombu with 8 cups of the water and let stand at room temperature until the kombu starts to soften, about 30 minutes.
2. 2
   Bring the water to a bare simmer over moderate heat; tiny bubbles will form on the bottom of the saucepan.
3. 3
   Remove from the heat and discard the kombu.
4. 4
   Add the remaining 1/2 cup of cold water to the saucepan, then add the bonito shavings and bring just to a simmer.
5. 5
   Immediately strain the dashi through a fine sieve and use right away.
