If you think that pasty blob of green garnishing your sushi platter is wasabi, think again.
The real-deal rhizome is as rare as it is pricey.
That’s why what you generally find on most sushi plates is actually a cheap concoction of horseradish, mustard and green dye, not the actual Japanese rhizome that’s extremely difficult to grow.
Nowadays, though, if you know where to look, you might find more of the real wasabi around. That’s because there’s now one grower in California cultivating it: Half Moon Bay Wasabi.
