Miso Soup with Potato and Komatsuna

みそ汁(じゃがいも・小松菜) · Misoshiru (Jagaimo, Komatsuna)

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

Miso soup is the everyday soup of Japan, and at preschool it appears on the lunch tray again and again with whatever vegetables are in season. This version pairs soft, thinly sliced potato with komatsuna, a mild Japanese mustard green that is a favorite in school kitchens. The potato simmers until tender in dashi, and the greens are blanched separately and added just before serving so they keep their bright color and don't turn mushy. If you can't find komatsuna, spinach or bok choy leaves work well in its place.

About the Japanese ingredients in this recipe
komatsuna (こまつな)
A mild Japanese leafy green (Japanese mustard spinach) with tender stems. Substitute: Spinach or bok choy.
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.
