The hot S&B Wasabi Powder is mixed with a little water and has a slightly stronger flavor than wasabi paste. Wasabi is known as Japanese horseradish, the green gnarled root of the wasabi plant. S&B Wasabi Powder can be used together with soy sauce as a dipping sauce for sushi and sashimi, but also for spicing up your soba noodles. Serve S & B Wasabi Powder in a bowl for seasoning Japanese dishes such as tonkatsu or shrimp.
