Egg Drop Soup with Tomato
トマト入り卵スープ
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
This is one of those soups that gets quietly slurped up at preschool lunch: a light consommé broth, sweet cream-style corn, ribbons of egg, and bright little cubes of tomato. A touch of potato starch gives the soup a silky body, which keeps the egg suspended in soft strands and makes it easier for little ones to scoop up. Peeling the tomatoes first means no tough bits of skin, just a mild, sweet-tart flavor that balances the corn.

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.
