What is Dashi? A Quick Guide

Importance of Dashi

Importance of Dashi Blog | Sake Inn

An essential backbone of almost any Japanese cuisine would be dashi. Dashi is a term used for stocks used in Japanese cuisine and this simple stock is essential in many Japanese dishes that you know and love. It can be made from steeping various ingredients in water. This versatile stock adds a subtle yet rich umami flavour to a wide variety of dishes. The best part of preparing your own dashi is that it takes less than 15 minutes. Having good stock helps provide your dishes with additional umami flavour, allowing your dishes to really stand out.

Japanese dashi stock is different from soup stocks from other cuisines as it is usually made with fewer ingredients, containing just one or two ingredients. It is usually made from ingredients like katsuobushi (dried bonito flakes), kombu (dried kelp), niboshi (dried sardines), shiitake (dried shiitake mushroom). You can make dashi using different combinations of the mentioned ingredients and it is entirely up to you! Read on to find out the different dishes you can

Katsuo Dashi (Bonito)

Bonito Flakes Dashi | Sake Inn

Bonito flakes, or Katsuobushi in Japanese, is thinly-shaved dried bonito fillet and there are many different varieties of katsuobushi depending on which part of the dried bonito fish it came from and how it is made. Bonito flakes add another layer of complexity to soup and dishes. 

How to

  1. In a pot, bring water to a boil.
  2. Just before the water starts boiling, just when bubbles start to rise, add the katsuobushi and bring it to a boil again.
  3. Simmer for about 30 seconds before turning off the heat.
  4. Let the katsuobushi sit in water for about 5 minutes before straining it over a fine-mesh sieve.

Kombu Dashi

Kombu Dashi | Sake Inn

Kombu is a type of kelp and you will usually see white specks or crystals on the surface of the kelp. These are crystals of glutamic acid that will help to contribute much to the umami flavour of the dashi. So remember not to rinse the kombu first. Kombu dashi adds a subtle flavour to many Japanese dishes that you know and love. It is also great in vegan and vegetarian dishes whereby the katsuo dashi would not be an option. 

How to

  1. Soak the kombu in water till soft. Do not rinse it. The white specks on its surface are not dirt but deposits that will help contribute to the umami flavour of the broth.
  2. Add soaked kombu and water into a pot and turn on the heat.
  3. Heat it until you see bubbles rising to the surface.
  4. Remove kombu from stock and it is ready to be used.

Niboshi (Dried anchovies/sardines)

Niboshi Dashi | Sake Inn

Made from dried little anchovies or sardines, such dashi would give you a bolder fish flavour and aroma as compared to the katsou dashi. There are different types of niboshi, made with different types of fish, each giving you a different flavour.

How to

  1. The heads and entrails of the fish need to be removed. 
  2. Prepare a saucepan or pot with water. Place cleaned niboshi in water.
  3. Steep for about 20-30 minutes. 
  4. Place the pot over medium heat and bring to a boil. 
  5. Once the water boils, lower the heat and let it simmer for few minutes. 
  6. Strain niboshi stock through a cloth over a sieve.
