Basic Dashi Stock

Awase Dashi

Base for good flavor dishes


Classic-style donabe (2.5-qt/ 2.5-liter capacity or larger)


About 1.8 quarts (1,800 ml)


  • 2 quarts (2 liters) cold water (soft water is preferred)
  • 2/3 oz (20 g) dashi kombu (dry kelp)
  • 1 oz (30 g) katsuobushi (dry bonito flakes for dashi stock)


  1. In a bowl, soak the kombu in the water for 2-3 hours.
  2. Transfer the kombu and the water to the donabe and set over medium heat.
  3. Just before the water comes to a simmer, remove the kombu. (about 25-30 minutes)
  4. Bring to a simmer, and turn off the heat immediately.  Add the katsuobushi all at once.
  5. Wait until the katsuobushi settles in the bottom of donabe (about 2 minutes).
  6. Strain through a fine-mesh shieve into a bowl.

Beautiful dashi stock is ready.

  • If you let the kombu sun-bathe for about 30 minutes before soaking in water, it would help increasing the vitamin D and umami level of the dashi stock.
  • For better infusion, once the kombu is soft during soaking in water, make many slits in the kombu with scissors. Kombu will release more flavors.
