With timely harvesting, proper handling, painstaking processing and careful drying techniques, the distinctive characteristics of fresh wasabi can be reproduced with remarkable accuracy.

When thoroughly blended to the right consistency a (slightly dry, not soupy, paste), cover the dish and set it aside for ten to fifteen minutes to allow the enzymatic action to activate the full flavors.
