Wasabi

Wasabi is a pungent, green condiment commonly served with Japanese cuisine, particularly sushi, sashimi, and tempura. It comes from the Wasabia japonica plant, a member of the brassica family (which also includes mustard, horseradish, and cabbage). Wasabi has a sharp, spicy flavor that clears the sinuses, similar to horseradish, but with a milder, more complex taste.
