Also called the “Japanese horseradish”, the wasabi comes from the Brassicaceae family of cabbages, horseradish and mustard. Despite so, there is no relation between the wasabi and the radish family. The root is known for its extremely strong flavour resembling hot mustard, creating a cool yet burning sensation through the nasal passages when eaten. Wasabi is used as a condiment, especially with sashimi. In restaurants, wasabi paste is usually made to order, as its flavour is lost as quickly as 15 minutes.
