Zunda mochi

Zunda mochi (ずんだ餅) is a type of Japanese confectionery popular in northeastern Japan. It is sometimes translated as "green soybean rice cake." It generally consists of a round cake of short-grained glutinous rice with sweetened mashed soybean paste on top. In some varieties, the green soybean paste entirely covers the white rice cake. In all cases, immature soybeans known as edamame are used. A closely related product is "kurumi mochi", which uses walnuts instead of soybeans.
