You need water to survive, so this must mean you also need dessert.

Here at Rooster, the word Rooster is synonymous with "Japanese Culinary Trends." So we'd be remiss if we didn't fill you in about Japan's newest and least dessert-y dessert, Mizu Shingen Mochi, otherwise known as "water cake." Well, if you need water to survive, so this must mean you also need dessert.

Although it might look like your Zima nightmare or something they feed starving models in their cages, it's really nothing more than water, sugar and agar agar. But because of the water-ness, it's being hailed as a "skinny" dessert … in addition to one that could support shark and mermaid life if it wanted to.

Adding to the diet vibe of this futuristic dinner friend is that if you don't eat it in 30 minutes, it disappears. That means either you eat it now, while you're crying over your breakup, or you don't eat at all in 30 minutes, while you're still crying over your breakup.

Mizu Shingen Mochi is a huge hit in Japan, where its success can be compared to the ubiquitous cronut. Currently, it's only made and sold in two Kinseiken shops in Yamanashi Prefecture of Japan. Wait times for the translucent glob can be over an hour.

The cake is clear and jelly-like, and served with a sugar syrup and kinako, a roasted soybean flour. But is it worth it to wait an hour for gel water and sugar-soy? We say yes if you fancy yourself as an intrepid explorer of gastro-trends … otherwise, the answer is still yes, because have you seen this thing? It's fucking water in an orb floating in sauce. We'll take 23 to go.

But let's pretend for one moment that you don't possess the limitless funds or free expanses of time that would permit you to travel to Japan for such a delicate fancy. Never fear, because you can make Japanese water dessert at home, far away from the urban throb of metro Tokyo. All you need to do is follow this video, then turn a hopeful gaze towards the future.
