Homemade Dashi Stock

Homemade Dashi Stock

  • serves 1
  • 35 minutes

Dashi is a flavouring stock used in Japanese cuisine, giving that quintessential Japanese flavour to your favourite foods. It all starts with “umami”, which when translated from Japanese to English, “savoury” is probably the closest word. One of the main combinations that make up umami is kombu kelp seaweed and katsuobushi bonito flakes, which make up most dashi soup stocks.


Katsuobushi Bonito Fish Flakes
Konbu Kelp
• Shiitake Mushrooms (For Vegetarian Option)
• Water (Filtered water if possible)

How To Prepare

  1. Start by opening up your pack of konbu kelp and wiping it down with a damp cloth to remove any impurities from the surface.

  2. Add a piece of konbu kelp approximately the size of a postcard with the water into a large pot and let it soak for about 20- 30 minutes in the cold water.

  3. Turn on the heat and allow the water to boil slowly.

  4. Just before the water boils, remove the heat and add your katsuobushi to the pan.

  5. Without letting the water fully boil over, allow the katsuobushi to simmer in the water for 1 minute.

  6. Remove the konbu and katsuobushi from the pan and strain through a fine sieve into a clean jug or pot.

Tips and Information

- To make vegetarian version of this classic Japanese dashi stock, simply substitute the katsuobushi bonito flakes for dried shiitake mushrooms and allow the flavour of the konbu kelp and shiitake mushrooms to infuse with the water. Allow the ingredients to soak in cold water for a few hours before heating and straining like the katsuobushi recipe. You can then use the shiitake for any number of Japanese dishes afterwards too.
