alt Hacker News> the “spice” due to wasabi is a different thing
But also, outside of Japan, 95% of the time the stuff with your sushi isn't wasabi, it's green-colored horseradish-and-mustard paste.

But the source of the spiciness is the same, at least: https://en.wikipedia.org/wiki/Allyl_isothiocyanate

Isn’t wasabi just horseradish. Are you saying the mustard is what makes it not true.

That's also true inside Japan. True wasabi is really hard to grow commercially and thus very expensive.
