Signs wasabi powder has gone bad

- Caking or clumping in the tin.
- Mixed paste dried out or turned off-smelling.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store wasabi powder
Sealed wasabi powder keeps its kick for about a year in a cool, dark cupboard, then goes flat. Once you mix it with water it's perishable — refrigerate the paste and use it within a couple of days, because the heat dies fast.
