Konnyaku is a plant that grows forming some kind of long cone, its interior is eaten in different ways in almost every Asian country. Its flavor is nothing special, the interesting thing about konnyaku is its gelatinous texture, which makes it a good choice to go along with almost any food. In Japan it’s usually eaten in oden and also in skewers (Tama Konnyaku), as it’s offered by this kind old woman in the streets of Shinjuku.
Cube-shaped konnyaku, that’s how I like it better.
