Manju is a traditional Japanese confectionery made from a thin layer of dough filled with sweetened red bean paste, typically made from azuki beans. The dough is often made from rice flour, giving it a soft and chewy texture. Manju can come in various shapes and sizes, and it is often enjoyed during festivals or as a snack. There are many regional variations of manju across Japan, each with unique fillings and flavors. Some popular types include kuri manju, which contains chestnut paste, and sakura manju, flavored with cherry blossoms. Manju is not only a treat but also a part of Japanese culture and culinary heritage.
