Sawaniwan Clear Soup (Elementary School Portion)
【小学校】沢煮椀 · Sawaniwan
By Aoi, licensed nutritionist · From a Japanese elementary school lunch menu
Sawaniwan is a classic Japanese clear soup built on fine strips of vegetables and pork simmered in dashi. One common explanation of the name is that "sawa" means "plenty" (as in takusan), a nod to the many ingredients cut into matching thin slivers so everything cooks evenly and is easy for children to slurp up with the broth. It is a familiar sight on school lunch menus across Japan, and with gobo, carrot, enoki, green onion and fragrant mitsuba in every spoonful, it is an easy way to get kids eating a wide range of vegetables. Sautéing the gobo, carrot and pork first deepens the flavor, and a light touch of potato starch at the end gives the soup a gentle body that keeps it warm and comforting.
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

Values are per serving (1.5× the Japanese elementary-school 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.
