Oh My !
Ive never had fresh wasabi grated just before you get your Sushi etc.
I did see , sometimes back . a reputable British food show
and yes they are
that went so some place in GB that's growing it. etc
in fresh water etc , and very secret as it so expensive and perishable.
they tasted it fresh ground , and I have no reason to believe the shows
presenter had any reason to exaggerate.
in Canada , rats.
however , is the real wasabi powder , when re-constituted
worth the effort ?
Im keen to know.
