I admit, I love it when people send me product samples. I’m a junkie for trying new foods and products. So when the folks over at Real asked me if I’d like to take 1/4lb of wasabi rhizomes for a spin, I said… SURE!
Most people have probably never eaten real wasabi. Most of the wasabi that you get in sushi restaurants or that is used as a flavoring for snacks and other products is really just white horseradish that is colored green. From a botanical perspective, Wasabi (Wasabia japonica) has little or no relation to white horseradish, and in terms of actual flavor, its really a lot different.
An apt comparison would be how most people perceive the cinnamon used on their French toast or as a common spice as real cinnamon, but in most cases it isn’t — real cinnamon comes from the rare bark of a tree that grows in Ceylon, as opposed to the bark of the Vietnamese cassia tree, the most common substitute.
Similarily, real Wasabi is grated wasabi rhizome, not white horseradish which most common wasabi powder comes from. Although both plants are from the crucifer family, they really taste very different. Wasabi has almost an “electric” taste with a very distinctive tingling sensation produced, which horseradish does not. What it does have in common with horseradish is its incredible pungency, although it is much more fleeting in effect.
One of the reasons why white horseradish is substituted for wasabi is that up until very recently, it only grew in Japan, and importing it was unbelievably expensive. In the last 10 years, two companies have started cultivating it in the US. One company is Pacific Farms FreshWasabi.com, which is based out of Oregon, distributes its product primarily in paste form and until recently did sell fresh wasabi rhizome.
RealWasabi.com is one of the few and I think the only company in the US that actually sells rhizome and grows domestically and ships to anyone who wants them. The company has its own farm based in the mountain region of western North Carolina, where the altitude and the temperate climate has proven to be good for growing Wasabia japonica.
Even domestically grown wasabi is a rare treat, and should be used sparingly. Wasabi Rhizome from RealWasabi.com costs $100 per pound and $55.00 per half pound. The fresh rhizomes have a shelf life of approximately 30 days in the refrigerator, if wrapped in a damp paper towel and kept in a plastic Zip-Lock bag.
