Buyer's guide

Powdered real wasabi will still be expensive, but should have the benefit of being used when you need it. True wasabi will contain wasabia japonica, while faux wasabi (and most of us will have to make do, won't we?) will be called Armoracia rusticana.

Storage

The roots will keep in the refrigerator for a few weeks, and can be grated as needed. Once exposed to the air, the flavour deteriorates quite quickly.
