RECIPE: Dashi Zosui (Japanese Rice Soup)


Zosui is a simple soy sauce-flavored rice soup often prepared for those feeling under the weather. Made with just a few ingredients, it is a nourishing, hydrating, and easily digestible soup that’s perfect for cold days. 

Compared to other Japanese rice porridges such as okayu or ojiya, zosui is characterized by its shorter cooking time that leaves the individual rice grains intact. Zosui looks like rice floating in clear broth, while other porridges become one homogenous mixture. 

To keep our zosui vegan, we use vegan dashi. We recommend this vegan dashi, which is made from a combination of umami-rich ingredients including konbu (dried kelp), shiitake mushrooms, beet sugar, and salt. When dissolved in water, these ingredients create a full-flavored stock in just seconds! 

To make dashi zosui, simply combine dashi stock and soy sauce together in a pot or nabe and heat for a few minutes. Then, add in cold cooked rice and boil until the rice becomes soft. If you’d like to add in extra ingredients such as small pieces of mushroom, vegetable, or protein, toss them in the soup during this step. It is also common to crack a raw egg directly into the boiling soup. Just be mindful that depending on what you add, the zosui may not be suitable for vegans anymore. Season with salt and pepper according to your taste and serve steaming hot with negi (green onions) sprinkled on top. 

The next time you feel a cold coming on, try warding it off with a warm bowl of dashi zosui!
