Awase Dashi – Japanese stock


Main Ingredients

Dry Kelp "Kombu"3 x 5 inch
Bonito Flakes "Katsuo-bushi"20 grams (0.7 oz.)
Water4 cups



  1. Do not wash kelp under running water as doing so will wash off the white powdery substances on its surface which holds a lot of the flavor. If the kelp seems dirty, gently wipe off the surface with a damp cloth

  2. Soak kelp in water for a minimum of 30 minutes, or you can leave overnight

  3. Slowly bring water to a boil over medium heat (it should take approximately 20 minutes)

  4. Remove kelp right before water begins to boil. You should see small bubbles rising from the pan. Do not vigorously boil kelp!

  5. After kelp is removed, bring stock to a boil

  6. Turn off heat and add bonito flakes

  7. Stir occasionally for first 5 minutes, then let sit for another 5 minutes or so until bonito flakes sink to the bottom

  8. Strain stock right away through a sieve lined with a paper towel or large coffee filter

  9. *Store in airtight container in refrigerator and use within 5 days.
