Wasabi is a spicy condiment derived from the root of the Wasabia japonica plant.

It has a very peculiar and unique flavour which is frequently described as sharp, spicy, pungent, and having a powerful kick that clears the sinuses. Wasabi's unique flavour profile is often compared to horseradish. It is used to add flavour and heat to various dishes in Japanese cuisine.

Wasabi should not be mistaken for the Japanese aesthetic concept of Wabi Sabi.
