DID YOU KNOW?

MOST ‘wasabi’ in the UK isn’t true wasabi ( Wasabia japonica) but horseradish. Real wasabi is not only costly but loses flavour fast so is best eaten fresh, making it hard to use in a condiment. Its heat hits your nose (due to allyl isothiocyanate vapours) — unlike chilli, where it’s in the mouth (down to capsaicin).
