Sushi Sonic 100% Real Wasabi Powder is 100% authentic freeze-dried wasabi, the rare, hard to grow, hot green rhizome so prized in the East for its pungency and medicinal properties. Simply mix 1 teaspoon of our tasty Sushi Sonic 100% Real Wasabi Powder with enough cool water to make a paste, let stand 10 minutes (to reach full flavor!) and enjoy.
