Kombu dashi – Japanese seaweed stock
A historical stock made from seaweed, water, and tuna flakes. A stock with a very strong umami flavour, considered a cornerstone of Japanese cuisine and used to make miso soups, ramen, fish soups, and noodles in stock.

Preparation time: Soaking the kombu for a few hours to a day, boiling the stock for a few minutes.
Level: Very easy
Amount: 5L stock
Ingredients:
50-70g dried kombu seaweed
A handful of dried tuna flakes (bonito flakes, katsuobushi)
5L water
A little sea salt if desired

Preparation:
- Place the kombu in cold water and soak it in a cool place for a few hours to a day. During this time, the flavours will be absorbed from the seaweed into the water.
- Remove the kombu, pour the liquid into a saucepan and bring to the boil.
- When the liquid has boiled, add the tuna flakes. Boil for two minutes.
- Pour the broth through a fine-mesh sieve and store at +4 degrees C for about a week, or freeze and store for a long time.
Use dashi to prepare Japanese dishes.
To make Japanese fish soup with Kombu dashi, get a piece of white fish fillet. For example, koha is good. Cut the fish fillet in half lengthwise and then into strips about 1 cm wide. Cut one carrot and about 150 g of white radish into small strips, and chop a small handful of parsley. Boil some quail eggs and cut in half lengthwise.
Bring the broth to the boil, add the fish and season the soup with a little sea salt and black pepper. Boil the fish for about 2-3 minutes. Add the shredded carrot, radish and chopped parsley. Add 2 tbsp soy sauce.
Let the soup stand for about 5 minutes and serve. When serving, pour the soup into bowls, garnish with quail eggs and herbs.
Ready!
