The grated root of wasabi, the Japanese member of the horseradish family, is light green in colour and has a strong, peppery flavour. Wasabi comes powdered or in a paste. I prefer to use the paste, as it’s quicker to use and lasts well in the fridge. When you think of wasabi you probably think of sushi; however, it’s also wonderful in dressings with soy sauce or lime juice, and is delicious mixed into mayonnaise. Be careful to avoid lumps of wasabi, though, or you’ll get the dreaded ’wasabi nose rush’, which you’ll have to ride out for a few seconds.
