Real wasabi paste is made from grating the fresh wasabi rhizome. On grating the rhizome also known as a swollen stem which can take up to 2 years to reach maturity, the volatile isothiocyanate compounds are released to give that wasabi kick – the pungent zingy flavour which everyone wants to experience. The wasabi paste always tastes amazing when it is freshly grated. The best grater to use on the rhizome is the traditional Japanese sharkskin paddle. Real wasabi rhizomes are difficult to find in stores, but at Wasabi Crop we are taking care of this to produce freshly grown wasabi rhizomes, leaves and stems.
