Miso Soup with Spinach and Koya-dofu

みそ汁(ほうれん草・高野豆腐) · Miso Shiru (Horenso, Koya-dofu)

By Aoi, licensed nutritionist · From a Japanese preschool lunch menu

This is a simple miso soup built around two staples of the Japanese school lunch kitchen: spinach and koya-dofu, a freeze-dried tofu that turns spongy and soft once rehydrated and soaks up the flavor of the dashi as it simmers. Both are cut small so the pieces are easy for small children to scoop up and chew. The spinach is blanched separately and added just before serving so it keeps its bright green color and does not turn the soup bitter or muddy, a small step that makes a big difference in how eagerly kids drink it.

About the Japanese ingredients in this recipe
koya-dofu (freeze-dried tofu) (高野豆腐)
Shelf-stable blocks of freeze-dried tofu that are soaked to rehydrate and soak up simmering broth beautifully. Substitute: Firm tofu, pressed and cubed.
dashi stock (だし汁)
Japanese soup stock, usually made from kombu (dried kelp) and/or bonito flakes; the base of most Japanese soups and simmered dishes. Substitute: Instant dashi granules dissolved in water, or a mild unsalted chicken or vegetable stock.
miso (みそ)
Fermented soybean paste. Salty and savory, it is Japan's everyday seasoning for miso soup and many simmered dishes. Substitute: Any light (white or awase) miso. Misos differ in saltiness, so start with a little less and taste. Some misos are made with barley or wheat, so check the label if you avoid them.
