Clear Soup with Bok Choy and Green Onion (Sumashijiru)
すまし汁(チンゲン菜・ねぎ) · Sumashijiru
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Sumashijiru is the clear cousin of miso soup: a bowl of dashi seasoned with just a little soy sauce and salt, so the flavor of the stock and the vegetables comes through. In this version the green onion simmers slowly until it turns soft and sweet, and the bok choy is boiled separately and added at the end so it keeps its bright green color and tender bite. It is a mild, easy-to-sip soup that pairs well with almost any Japanese main dish, and one that even very young children can enjoy.
Wheat-free, but uses soy sauce (made with wheat). Japanese school-lunch allergy menus usually allow it, so check with your doctor. How to read the labels

- 2
Slice the green onion into thin rounds.
- 3
Put the dashi stock and the green onion from step 2 into a pot and simmer over low heat for about 15 minutes.
- 4
Add the seasonings and simmer briefly, then add the bok choy from step 1 and stir to combine.

Values are per serving (1.5× the Japanese preschool portion); an adult serving is double. They were calculated by a licensed Japanese nutritionist using the Standard Tables of Food Composition in Japan. "Salt equivalent" is sodium × 2.54, the standard Japanese measure. Allergen flags cover egg, milk and wheat only and come from the nutritionist's records. Soy sauce and miso are made with wheat but are usually allowed on Japanese wheat-free school menus, so check with your doctor.
