Oni Manju (Sweet Potato Steamed Cakes)
鬼まんじゅう(乳なし) · Oni Manju
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Oni manju are homey steamed cakes packed with chunks of sweet potato, a beloved snack from the Nagoya area of Aichi Prefecture. The name means "ogre buns": the knobbly pieces of sweet potato poking out of the batter are said to look like an ogre's horns or spiked club. Children love the soft, lightly sweet dough and the tender bites of potato, and since this version is made with pancake mix and soy milk, it is simple to put together and free of dairy.

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.
