A Guide to Dashi

15th November, 2021

Dashi is an essential part of many Japanese dishes. Unlike soup stock from other cuisines, dashi is only made from two ingredients and takes around 10 minutes to make.

This blogpost will explain what dashi is, the different types of dashi stock, how they’re used in Japanese cuisine and how chefs can incorporate them into their recipes to add an extra depth of flavour to any Japanese or fusion dish.

What is dashi?

Dashi is a Japanese soup stock that is typically made of fish such as dried bonito flakes or sardines, kombu, dried shiitake mushrooms, or a combination of both vegan/vegetarian and seafood ingredients.

The soup stock adds an extra depth of favour to dishes, known as umami. Let’s explore the different types of dashi stock:

Types of dashi stock

  • Awase Dashi: made of different combinations, but mainly bonito flakes and dried kelp, this is the most popular dashi stock used in a variety of soup-based dishes.
  • Kombu Dashi: only made of one ingredient, this is the easiest dashi to make and has the most subtle flavour. Ideal for vegetarian and vegans, the soup stock is also used to give a gentle flavour to seafood dishes.
  • Katsuobushi Dashi: made of dried bonito flakes, this is an all-purpose dashi stock that can bring an umami flavour to almost any dish.
  • Shiitake Dashi: made of dried shiitake mushrooms, it’s mostly used as a base for boiled foods. This is ideal for vegetarian and vegan customers who like meaty flavours.
  • Niboshi Dashi: made of baby dried sardines, this soup stock brings a strong fishy flavour to dishes – which means it should be used carefully.

How to Use Dashi in Your Restaurant Meals

Below is a list of dishes containing dashi stock that you can incorporate in your restaurant meals:

  • Awase Dashi: this is great for dishes such as miso soup, tamagoyaki (Japanese omelette) and oden.
  • Kombu Dashi: ideal for vegetarian and vegan dishes such as vegetable ohitashi and yodofu; but also great for seafood dishes such as clam soup and salmon kombu roll.
  • Katsuobushi Dashi: perfect for giving an aromatic flavour to any clear soups, simmered vegetable and noodle soup dishes.
  • Shiitake Dashi: mainly used to enhance the flavour of kombu or katsuo dashi, this soup stock is great for fusion dishes such as salmon tartare bites, shiitake broth & miso tofu and vegetarian udon.
  • Niboshi Dashi: great for adding a strong fishy aroma to miso and udon soups, rice bowl dishes and simmered dishes.
