Mizu Yokan is a traditional Japanese dessert, or wagashi, as it is known in Japanese cuisine. Yokan is a general term which refers to this jelly dessert made of red azuki beans, agar, and sugar. The red azuki beans are in the form of tsubuan (smooth red bean paste) or koshian (coarse red bean paste). In other variations of yokan, the red beans are substituted with a white kidney bean paste which is known as shiro-an. Yokan is typically molded into a long rectangular block which is then sliced prior to serving.

Mizu Yokan is a type of yokan which has a higher water content than traditional yokan. It is often chilled and served during the hotter summer months and is quite a refreshing dessert.

There are several flavor varieties of yokan and mizu yokan. Examples of additional ingredients include foods such as chopped chestnuts, sweet potato, and fruits. Another popular flavor addition is green tea or matcha powder.

  • 1 1/4 cups water

  • 1 cup brown sugar

  • 1 1/2 cups (3/4 pound) anko (sweet azuki red bean paste)

  5. In a medium pan, add the kanten pieces or kanten powder with 1 1/4 cups of water and bring to a boil, making sure to stir constantly. Turn down the heat to low. Simmer until the kanten dissolves completely. All the while, make sure to stir the kanten and water.
