On the plate

Starchy flesh, slightly bitter, tasting of hazelnut and potato.

Avoid: Serving it unblanched: its slight bitterness puts people off; blanch it first to soften it.

In Japan its long sprout pointing upwards makes kuwai a lucky charm: people wish for success that shoots up straight like it.
