Karukan (Japanese Steamed Yam Cake)
かるかん · Karukan
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Karukan is a traditional steamed confection from Kagoshima in southern Japan, made from grated yam, rice flour and sugar. The nagaimo gives it a light, springy, almost marshmallow-soft texture that is easy for little ones to bite and chew, and the sweetness is gentle rather than sugary. It is made without egg, dairy or wheat, and it works well as an afternoon snack (oyatsu) for preschoolers.

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.
