How to Make Dashi

Dashi

Dashi, broth of fish or vegetables, is an important component when cooking Japanese food.  Dashi is the base flavor of a lot of Japanese dishes, and it is hard to omit.  Whether you make it from scratch or use more convenient instant granules or packets, Dashi will be needed if you’re cooking Japanese food. We’ll show you how to make 4 kinds of Dashi here, and they will be used in different dishes.

Dashi ingredients are found at Japanese or Asian markets, but you can also buy them online today. Check out our Dashi recommendations on Amazon.com (#CommissionsEarned)

Katsuo (dried bonito flakes) Dashi

Katsuo Dashi is probably the most common and versatile kind of Dashi of all the Japanese broths.  If you don’t know which Dashi to make, Katsuo Dashi may be the most flexible one for different kinds of dishes.  It has plenty of fish Umami (savory flavor) and becomes a base layer of flavor before seasoning it with Soy Sauce, Miso, salt, etc.  When cooking meat and vegetables with Katsuo Dashi, it really doesn’t taste too strong.  It stands in the background and gives dishes more complex tastes.

Katsuo Dashi is often used in Miso Soup, Nimono (cooked meat and vegetables in broth), Dashimaki rolled egg, and many other dishes.  Here, we made a very simple but tasty Imo no Nikkorogashi (boiled potato in seasoned broth) with Katsuo Dashi.

Imo no Nikkorogashi

4 medium potatoes
2 cups Katsuo Dashi
2 Tbsp Soy Sauce
1 Tbsp Mirin
1 Tbsp sugar
 
Peel potatoes and cut each into 4 pieces.
Boil Dashi and add potatoes.  Cook covered until potatoes becomes soft at medium heat.
Add all the seasonings and stir. Cook until the liquid is reduced to less than half. Cool in the pot, covered, to let potato absorb the flavor. 

Kombu (dried sea kelp) Dashi

Kombu Dashi is a milder broth and has a more subtle flavor. It doesn’t use fish so it is a great option for vegetarian dishes.  You don’t need very much Kombu to make Kombu Dashi because the Kombu expands.  Kombu Dashi is good by itself but works especially well when mixing with other Umami packed ingredients such as meat and seafood.  Adding Katsuo bonito flakes to Kombu Dashi makes a richer Dashi, and that is called Ichiban Dashi.  Ichiban Dashi is often used to make soups that need a more pronounced Dashi flavor.

Kombu Dashi is usually used in Nabemono, and hot pot dishes, such as Mizutaki and Yudofu.

Kombu Dashi
2 cups (480 ml) water
8 g Kombu dried sea kelp
 
In a pot, add water and Kombu, and let soak for 30 minutes.  Put the pot on a stove at medium heat and cook until just before boiling.  Remove Kombu.

Niboshi (dried sardine) Dashi

Niboshi Dashi is a broth made with small dried sardines.  It may have a stronger fish aroma and taste than Katsuo Dashi.  Niboshi Dashi is good for dishes that need a little more kick of fish flavor.  It is important to remove the head and innards (guts) from the dried sardines before cooking so that the broth doesn’t get a bitter taste or undesirable fishy smell.

Niboshi Dashi is great for simple Miso Soup to enjoy the soup itself.  We made Tofu and Wakame seaweed Miso Soup in the video.  Ordinary Miso Soup turned into an upgraded soup by using Niboshi Dashi and a little Katsuo dried bonito flakes.

Niboshi Dashi
2 cups (480 ml) water
15 g Niboshi dried sardines
 
In a pot, add water and Niboshi, and let soak for 30 minutes.  Put the pot on a stove at medium heat and let boil for a few minutes.  Remove sardines. 

Shiitake Mushroom Dashi

Shiitake mushroom Dashi is the water in which dried Shiitake mushrooms are rehydrated.  This very distinctive mushroom flavored Dashi is not for everything because the taste is quite strong. It’s often used when cooking vegetables or together with the rehydrated Shiitake mushrooms to enhance the mushroom flavor even more.

Shiitake mushroom Dashi is great for cooking vegetable Nimono (cooked meat and vegetable in broth), Mentsuyu noodle sauce, and Takikomi Gohan seasoned rice.

Shiitake Mushroom Dashi
2 cups (480 ml) water
25 g dried Shiitake mushrooms
 
Rehydrate dried Shiitake mushrooms in water until soft.  Remove mushrooms.

Instant Dashi

There are instant versions of any kind of Dashi, often granular or powder form, available at Japanese markets. That is very convenient when cooking with limited time during school or the work week.  Making Dashi from scratch is becoming a luxury in today’s busy life style. Although real Dashi always beats the artificial flavorings, instant Dashi is the next best thing to homemade Dashi.
 
All of the Dashi above can be made with ingredients soaked in water overnight in the fridge.  A little prep the night before will help greatly for dinner the next day.  Also, Dashi doesn’t have to be made with a single ingredient and water.  You can always combine different ingredients to create your own flavored Dashi.  Combinations of different seafood ingredients, such as Katsuo and Kombu or Katsuo and Niboshi,  always work well.  Also the combination of fish and vegetable such as Niboshi and Shiitake mushroom may create layers of different tastes in Dashi which could deepen dishes further. It’s a great area in Japanese cooking to enhance your cooking and build your own signature flavor.
