What is Dashi?

First of all, you may be wondering what dashi is and how it plays such an integral role in Japanese cuisine. It is a type of broth that forms the base of many standard Japanese foods, such as miso soup. It can be made from a variety of ingredients, but all dashi has a strong, savory flavor that is key in Japanese soups, noodle dishes, hotpot-style dishes, and more. It often looks quite watery, but don't be fooled; It is full of flavor.

Types of Japanese Dashi

To fully understand dashi, it is important to explore the various types. The different types vary depending on the main ingredient used to make them. These can be divided into awase (combined), kombu , shiitake or iriko dashi .

Dashi Awase (Combined Dashi)

Awase (combined) dashi uses both kombu (Japanese seaweed) and katsuobushi, or dried bonito flakes, to create a unique and complex flavor. Katsuobushi is a type of dried fish flakes commonly used in Japanese cuisine. It is made by first creating a kombu broth using the hot method, and then adding the katsuobushi when the kombu is removed. The katsuobushi should be kept in the broth while it boils and then left to sit until it absorbs the water and sinks. Then, it must be strained to remove the flakes. Awase dashi is the most common type of dashi in modern cuisine and is usually the first variety that comes to mind.

Dashi Kombu

Dashi kombu is one of the oldest and most traditional styles of dashi. It's a simple style based on just two ingredients: kombu and spring water. Kombu is a type of seaweed and is a popular ingredient in Japanese cuisine. There are two ways to make dashi kombu: hot (nidashi) and cold (mizudashi). Mizudashi is made by soaking kombu in water overnight in the refrigerator. The shorter method, nidashi, involves soaking the kombu in cold water for a few hours or slowly heating the water and removing the kombu just before it boils.

shirodashi

What is White Dashi and how is it different?

If you are interested in Japanese cuisine, you may have also heard of shirodashi or white dashi. White dashi is slightly different from the original traditional dashi. It is more complex in its ingredients and cooking method and is often used in different ways.

Shirodashi is usually made with a dashi base but has other ingredients such as mirin, light soy sauce and sugar added. It does not alter the color of a dish when used and is therefore popular on light colored dishes or foods where color is considered important. These include foods like tamagoyaki (rolled omelette), chawanmushi (steamed egg custard), and udon noodles.

How to use Dashi

Dashi can be used in a variety of ways in Japanese cuisine. As it is commonly considered a soup broth, it is used in almost all Japanese soups and liquid-based dishes, including oden, udon, soba, ramen, stews (nimono), shabu-shabu, and several others.

However, it can also be mixed with flour to create a base for more solid foods, such as okonomiyaki and omelettes. If used sparingly and mixed with the right ingredients, it can create a base for dipping sauces or cooking vegetables. One of the most common ways you'll see dashi used is in miso soup, the ubiquitous accompaniment to almost every meal in Japanese cuisine.
