What is Sumashijiru?

Sumashijiru is a traditional Japanese clear soup made with dashi broth, seasoned with salt and soy sauce. "Sumashi" means clear, and "jiru" stands for soup. It is a simple yet delicious dish that allows you to experience the delicate flavor of dashi, enjoyed not only as a regular meal but also at celebrations.

You can use any type of dashi for this dish, but I highly recommend using awase dashi, which combines kombu dashi and bonito dashi. When made with these ingredients, the umami flavor becomes even more pronounced and exquisite.

This recipe includes instructions on how to prepare awase dashi. However, if you would like to learn more about the process of making dashi in detail, please refer to the linked pages titled "Kombu Dashi" and "Bonito Dashi."

For clear appearance

When making this soup, it is recommended to use light soy sauce. Light soy sauce has a lighter color and slightly higher salt concentration compared to regular soy sauce, making it suitable for achieving the clear appearance of the soup.

However, if you don't mind the soup having a slightly darker color, you can also use regular soy sauce. There won't be a significant difference in flavor.

Typical ingredients

The ingredients commonly used in sumashijiru include mitsuba (Japanese parsley), kamaboko (fish cake), shiitake mushrooms, small shrimp, and fu (wheat gluten).

Since this soup dish focuses on enjoying the flavors of the broth itself, it is preferable to use a smaller quantity of ingredients. When the emphasis is on the ingredients, it is called 'suimono,' which is considered a different type of soup in Japan compared to sumashijiru.

Choosing soup bowls

This soup is a dish that stands out for its clear broth. While you can certainly enjoy it in any bowl, I highly recommend using one with a non-dark interior. Opting for a bowl with a light-colored interior will enhance the transparency of the broth and make the dish look more vibrant.

Step 4
Turn off the heat and strain the mixture through a sieve lined with paper towels or a cloth (such as cheesecloth). Alternatively, if you don't mind some fine bonito flakes remaining, you can simply use a fine-mesh strainer. Awase dashi, which combines kombu dashi and bonito dashi, is now ready.
