Wasabi

Wasabi is a root plant with a pleasant aroma and a sharp, fiery flavour. In early 17th century Japan, it became a popular accompaniment to sushi, prompting the spread of its cultivation. Wasabi is available fresh, and can be grated like horseradish, as a paste or in powder form, which is mixed with lukewarm water to make a light green paste. It is also mixed with soy sauce and served as a condiment with sashimi and sushi. When used for seasoning, wasabi can stimulate the appetite and it is also known to prevent food poisoning.
