Raindrop Cake: A dessert that disappears in 30 minutes!

The cake that appears as a solid bubble of water is taking the internet by storm.

The Japanese Raindrop Cake -- a transparent drop cake that looks like a bubble of water -- has taken the internet by storm.

It is made up of water from the Southern Japanese Alps, which is solidified just enough to be given a shape. The water from these mountains is believed to be so tasty that it does not need any flavouring.

In theory, the water is solidified using agar-agar and is then put into a spherical mould to be set.

The Japanese Raindrop Cake is traditionally known as Mizu Shingen Mochi -- Mizu in Japanese means water and Mochi is a kind of dessert made of rice flour.

The transparent water cake is usually served with roasted soybean powder (known as Kinako) and black sugar syrup (known as Kuromitsu). It also goes well with honey and peanut powder.

The Japanese Raindrop Cake is sold at very few stores -- it is also available in places outside Japan now -- and cannot be packed for 'to-go' parcel because of its short shelf-life.

Its self-destructing mechanism is a matter of fascination. It is believed to dissolve into the water if not eaten within 30 minutes of being served.
