What is Uiro?
Uirō , also known as uirō-mochi , is a traditional Japanese steamed cake made of various types of rice flour and sugar. It is chewy, similar to mochi , and subtly sweet, but is not pounded to create a paste. Flavors include azuki bean paste, green tea ( matcha ), yuzu , strawberry, and chestnut. Nagoya is particularly famous for its uirō , and there are other regional versions, notably in Yamaguchi and Odawara, although Odawara's uirō is better known as a medicine. It can be purchased in traditional Japanese confectionery shops throughout Japan.
