The raindrop cake is a crystal clear cake shaped as a water droplet. Yamagoya restaurant in London is now making the dessert, which only contains water, and sugar, and agar powder – a natural gelatin substitute.
The little ingredients make the cake basically tasteless and calorie-free. It is usually served with sweet molasses syrup and roasted soybean flour.
It is inspired by the Japanese dish "mizu shingen mochi."
You can buy a raindrop cake for £2.30 alongside one of Yamagoya’s traditional ramen.
