Do you know Yamaimo? Well, it is a root vegetable with a structure like daikon but if you grate it, the texture becomes very gooey and sticky. It taste mild but before grating it you have to soak it in cold water with vinegar otherwise it will be very itchy. The plant look like this.
Famously, yamaimo is the ingredients that makes the Okonomiyaki pancake. You can find yamaimo poured on top of udon. During my long stay here in Japan, I grew to like yamaimo eaten raw, with raw egg yolks. Combined they taste creamy.
