How to grate and store wasabi:
Gently grate wasabi in a circular manner by using a fine-toothed grater like shark skin.
Put it in the container and wrap it for 3-5 minutes to prevent wasabi from drying out.
Grating method to create the most flavourful and sharp taste:
When grated, enzyme action when wasabi is exposed to the air generates spiciness.
The finer the grating, the spicier the wasabi.
Add lemon juice to facilitate the oxidation of Vitamin C to draw the spiciness of the wasabi out.

Dissolved wasabi must be used within a day or sealed and stored in the refrigerator for use the following day.
Add lemon juice to facilitate oxidation of Vitamin C and bring the spiciness out.
