Wasabi - Wasabi preparation, Kinjirushi

Wasabi is a green root crop with a distinctly pungent flavor. Originally native to Japan, it only thrives in flowing water. The root, which is comparable to horseradish, is now also cultivated in New Zealand and the USA. Wasabi is traditionally used as a seasoning for sushi and roasted nuts and legumes. The typical wasabi spiciness is caused by the volatile mustard oils it contains and it burns the throat and nose. Wasabi is offered as fresh root, powder or paste.
