  • 2 quarts filtered water plus 2 quarts more water for second batch
  • 1 cup packed bonito flakes
  • 1 ounce dried kombu, optional


  • Place optional kombu in saucepan with water.
  • Heat but do not let water boil.
  • As bubbles appear in hot water, but just before it simmers, remove optional kombu, setting it aside.
  • Add bonito flakes. Keep heat on under pot and allow water to come to boil. Then turn off heat immediately.
  • Bonito flakes will absorb water and slowly sink. Allow 3-5 minutes for this process.
  • Strain broth, reserving bonito. This is First Dashi.
  • For a second, stronger broth put 2 quarts more water back into pot with reserved kombu and bonito.
  • Heat water to barely a simmer (do not boil) for 10 minutes. Strain. This is Second Dashi.


*If you happen to be on the GAPS Introduction Diet, kombu is not allowed.
