Authentic wasabi paste, made from the rhizome of the Wasabia japonica plant, offers a pungent, sinus-clearing kick perfect for sushi, sashimi, and marinades. Proper storage is key to preserving its vibrant flavor and characteristic heat.

Storage Time

Once opened, wasabi paste typically lasts for 1-2 weeks in the refrigerator, though its potency may diminish over time. Unopened, shelf-stable tubes can last for several months.

Temperature

Always store opened wasabi paste in the refrigerator, ideally between 0-4°C (32-40°F).

Freezing

While freezing wasabi paste is possible, it can significantly alter its texture and slightly diminish its potent flavor and heat. To freeze, transfer the paste to an airtight container or ice cube tray, ensuring minimal air exposure. Thaw slowly in the refrigerator overnight before use. Expect a softer, more watery consistency upon thawing.

Signs of Spoilage

• Unpleasant, sour, or fermented odor.
• Visible mold growth, often appearing as fuzzy green or black spots.
• Significant discoloration, turning a dull brown or grey instead of its vibrant green.
