Japanese cuisine never ceases to amaze, and this cake is no exception. Although it looks like a giant drop of water, it is actually a form of rise cake, or Shingen Moshi. This cake is called Mizu because it has a water base. The water comes from the Japanese Alps and the cake has a very delicate texture.
The cake is made with agar, a common analog to gelatin in Asian cuisine, which makes the cake melt in your mouth. It looks like it might pop if you poke it with a needle, but it can actually be eaten with a spoon! You better be quick eating it, however, because it melts away like ice and dissolves into sweet water after 30 minutes.
