Fresh wasabi horseradish (rhizome) - 150g - classicly paired with sushi and sashimi - 10 days lead-time

Wasabi is generally sold either as a rhizome or stem, which must be very finely grated before use, as a dried powder, or as a ready-to-use paste in tubes.

In some high-end restaurants, the paste is prepared when the customer orders and is made using a grater to grate the stem; once the paste is prepared, it loses flavor in 15 minutes if left uncovered. In sushi preparation, chefs usually put the wasabi between the fish and the rice because covering wasabi until served preserves its flavor.
