Kashiwa Mochi is a traditional Japanese confectionery made of mochi that is filled with sweet red bean paste and wrapped in an oak leaf.
The rice flour used to make Kashiwa Mochi is called joshinko. Joshinko is a rice flour made from milled non-glutinous short-grain rice. Unlike soft and stretchy mochi made with glutinous rice, the mochi made with joshinko flour is chewy and firm. It is also used to make dango and daifuku.
Kashiwa Mochi is commonly eaten during Kodomo no Hi (Children’s Day or Boys Day), and represents strength, longevity and good fortune.
