Hokkaido Rice Mochi Puff (Red Bean) Light as air and snow-white, these mochi puffs look like fluffy snowflakes and made with Hokkaido Anko (red beans). Slightly sweet and creamy, this delicious snack is made using domestic Japanese rice flour from Hokkaido and a secret process is used to transform it into the crisp and airy texture of this cloud-like confection.
