The other day, when I went to the Japanese Restaurant with my colleagues who are all non-Japanese people, I was asked about "Zenzai" and "Anmitsu" from them, but I could not explain in detail because I'm not sure about it even I am a Japanese...
So I googled it, and here is the answer;
Zenzai: Stewed sweet red beans and eat with Japanese mochi which is soft rice cake in Japan.
Anmitsu: It is a kind of Japanese sweet which putting Kanten Jelly, Fruits like orange and beans in the bowl and then to put the syrup on it.
Both are very popular Japanese sweet, so worth to try it :)
