Sumashijiru (Clear Soup) with Komatsuna and Onion

すまし汁(小松菜・玉ねぎ) · Sumashijiru

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

Sumashijiru is the clear soup of Japanese home and school cooking: dashi seasoned lightly with soy sauce and a pinch of salt, so the flavor of the stock and vegetables comes through. Here it carries thin slices of onion, simmered until soft and sweet, and short pieces of komatsuna, a mild Japanese leafy green (spinach or bok choy leaves make a fine substitute). In preschool kitchens we blanch the greens separately and stir them in just before serving, so they keep their bright color and don't turn bitter or muddy the broth. Cutting everything small makes it easy for little ones to scoop up with a spoon.
