Wasabi - can I freeze it for future?

I bought about 5 medium wasabi stalks back to Australia (yes - declared to customs/quarantine) I have used one already (fresh) and frozen the others. I have no idea but is frozen/thawed wasabi any good does it keep well - or just throw away? Obviously fresh is best but not an option here...

This plan sounds good, but won't apply to you since you've already frozen it:

"'Can it {fresh wasabi}be frozen if I can’t eat it all?'"

We do not recommend freezing whole rhizomes. Grated wasabi can be frozen if it is done immediately after grating. Grate the wasabi and wrap with cling film. Make sure the wasabi is protected from the air by wrapping tightly."

I guess that they'll be mushy when you defrost, and won't grate well.

I have no idea if this will work, but try grating one while it's still frozen. If it works, you won't have to defrost a whole one every time you want a bit.

Just as bibimbob said; wash the wasabi root and wrap it and freeze. When using, grate the frozen root. Whenever wasabi is exposed to air, it loses potency, so you do not grate and freeze.

Same thing with powdered wasabi. You mix it with water and use it right away. Wasabi left for a long time has no punch.

You can buy fresh wasabi in Japanese or even Korean markets in CA.
