Sweet Potato Puree
さつまいものペースト · Satsumaimo no Pesuto
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
This is one of the simplest dishes in the preschool kitchen: boiled Japanese sweet potato blended with kombu dashi until silky smooth. The sweet potato brings all the sweetness it needs, and the kelp stock adds a gentle savory depth without any salt, so the flavor stays mild for little ones. The soft, spoonable texture makes it an easy side for young children who are still getting used to chewing.
