Wasabi preparation, cut (Kizami Wasabi), with real wasabi

Wasabi is a green root vegetable with a distinctly pungent flavor. Originally from Japan, it thrives only in flowing water. This root, similar to horseradish, is now also cultivated in New Zealand and the USA. Wasabi is traditionally used as a condiment for sushi, roasted nuts, and legumes. The characteristic wasabi pungency comes from the volatile mustard oils it contains, causing a burning sensation in the throat and nose. Wasabi is available as a fresh root, powder, or paste. The leafy part of the plant is also used in the paste and powder, making it somewhat milder compared to the paste and powder, while still retaining its interesting aroma.
