What is Kakitamajiru?

Kakitamajiru is a traditional Japanese soup made by thickening seasoned dashi broth with starch and adding beaten eggs. "Kaki" means to stir, "tama" is short for 'tamago,' meaning eggs, and "jiru" refers to soup.

While many people might associate Japanese soups with miso soup, learning to make this dish can expand your repertoire of Japanese soups. The combination of dashi and eggs pairs incredibly well, resulting in a delicious flavor.

Enhancing Umami Flavors of Dashi

The dashi broth typically used in making kakitamajiru is bonito dashi (awase dashi, which combines kombu dashi and bonito dashi, is also acceptable).

Bonito dashi contains an umami component called inosinic acid, while eggs, the primary ingredient of this soup, contain another umami component known as glutamic acid. These umami components are delicious on their own, but combining two (or more) different umami components is known to enhance their respective flavors and make them even more delicious through a synergistic effect. In other words, eggs and bonito dashi complement each other perfectly.

The combination of eggs and bonito dashi is a classic pairing found in various Japanese dishes such as Chawanmushi (savory egg custard) and Dashimaki Tamago (rolled omelet with dashi). It is so delicious that I highly recommend trying it in this recipe as well.

The recipe includes instructions on how to make bonito dashi, but if you would like to learn more, please refer to the linked page.

Ingredient Options

Kakitamajiru is a simple soup that primarily features the flavors of egg and dashi broth. Traditionally, it is enjoyed with just mitsuba (Japanese parsley) or green onions (scallions).

However, you can also enhance it with a variety of other ingredients. In Japan, chicken, carrots, onions, spinach, tofu, kamaboko (fish cake), shiitake mushrooms, enoki mushrooms, and wakame seaweed are sometimes added. A heartier version of this soup can be a modern and nutritious meal option. Feel free to experiment according to your preference.

To store

You can store it in the refrigerator for up to 2 days.

Tips on how to make

  • Add starch dissolved in water to the dashi broth to thicken it. The thickened dashi will prevent the beaten egg from sinking to the bottom of the bowl, allowing it to float until it is time to eat.
  • The beaten egg should be poured into the pan gradually and evenly. This will prevent the egg mixture from clumping together and create a fluffy texture. In Japan, it is common to pour the beaten egg gradually using a chopstick to let it trickle down.
  • After pouring the beaten egg into the pot, make sure it has set before stirring. Stirring before the egg mixture has set can make the soup cloudy.
