This Mustard Wasabi Rub Will Open Your Nostrils

Last Modified On: July 10, 2026

A fantastic balance of spicy, sweet, salty and savory flavors

Hate to burst your Japanese bubble, but most of the “wasabi” served in Japanese restaurants in North America is grated horseradish dyed green and mixed with mustard powder and cornstarch. Womp-womp. It still tastes good! It’s just that real green wasabi is hard to cultivate outside of Japan, so western horseradish, which is closely related, pinch hits in most restaurants. The wasabi powder you find in American grocery stores is similar: It’s a mix of horseradish, mustard powder, and maybe a little real wasabi powder. That’s why it’s pale green instead of bright green, as in the photo here.
