Koruille

Koruille is a traditional Japanese confectionery made from sweet red bean paste, typically azuki beans, wrapped in a thin layer of mochi (glutinous rice flour). The name "koruille" is derived from the Japanese words "kuri" meaning "straw" and "ille" meaning "to wrap," reflecting the process of wrapping the bean paste in mochi. This confectionery is often associated with the Japanese New Year's celebration, particularly the Osechi-ryori, a traditional gift of food given to visitors during the New Year.

The preparation of koruille involves several steps. First, the azuki beans are cooked and then pounded into a smooth paste. This paste is then mixed with sugar and sometimes other ingredients like cinnamon or ginger for added flavor. The mixture is then wrapped in a thin layer of mochi, which is made by mixing glutinous rice flour with water and shaping it into a thin sheet. The mochi is then wrapped around the bean paste, creating a cylindrical shape.

Koruille is typically served chilled and is known for its chewy texture and sweet flavor. It is often enjoyed as a snack or dessert and is also used as a filling for other Japanese sweets, such as daifuku mochi. The confectionery is a popular item in Japanese bakeries and supermarkets, particularly during the New Year's season.
