Real Wasabi
Following the DC Trivia Question #2, I thought I’d follow up with a bit more of a detailed post regarding the nature of

First off, long ago, I had the chance to tour the Pacific Farms Wasabi Ranch in Oregon, so I’ve known for quite sometime that the green glop at sushi joints is fake but since I’ve never had the chance to taste 100%
I’d venture to guess that less then 50% of Americans know that “American” Wasabi is indeed a horseradish powder with green food coloring. But in this case, it may be better to remain blissfully ignorant.
What is Wasabi?
Wasabi (Japanese: ?? or ???; scientific name Wasabia japonica (syn. Cochlearia wasabi, Eutrema japonica)) is a member of the cabbage family. Commonly known as Japanese horseradish, it is green and has an extremely strong flavor. Its hotness is different from that of the chile pepper, which burns the tongue; wasabi produces vapors that burn the sinus cavity instead. The plant grows naturally along stream beds in mountain river valleys in Japan. There are also other species used such as W. koreana, and W. tetsuigi. The two main cultivars in the marketplace are W. japonica var. Duruma and Mazuma, but there are many others.
From Wikipedia
Real wasabi is one of the rarest and most difficult vegetables in the world to grow, which is why that fake stuff was created. It’s like Krab (You know, Crab with a K) – the fake crab meat. It’s cheaper and easier.
It’s surprisingly spongy, but that may be because of the freezing & defrosting processes it underwent on its way from Japan.
The Science of Wasabi ** Chile Pepper Magazine – Oct 2005
Wasabi hits the nasal passages hard. While chile peppers heat with capsaicin, which attaches to the saliva and stays in the mouth, wasabi, which is in the mustard family, heats with mustard oil, which is a gas rather than an oil and which goes right up the nose as the taste buds on the front of the tongue are tickled too. This is because of allyl isothiocyanates, which give pungency, and glucosinolates, which are also found in mustard oils and horseradish. While the heat of chiles lingers, the hot-chill of wasabi gasses off, leaving a pleasant green taste behind. Wasabi is in the cabbage family, but scientists have also traced its family roots to some grandparents of arugula as well. There are some indications that eating wasabi may be helpful in blood clotting and in cardiovascular care, as well as protecting against breast cancer, stomach and colon cancers and even tooth decay.

The pile on the left is fresh grated wasabi rhizome and the pile on the right is the sushi bar wasabi. Visually, you can see just how pasty and fake the sushi bar stuff is, while the real rhizome looks pleasant and appetizing. Smell wise, the real rhizome has the fake stuff beat hands down. The nostrils are assaulted with one whiff, causing the eyes to water instantly. Taste also goes to the real rhizome – the sushi bar stuff has a bit more ‘heat’ but the real stuff definitely has much more flavor.
If you are going to cook with wasabi (I highly recommend you do) order the wasabi paste from Pacific Farms and get yourself of this months Chile Pepper Magazine. The Wasabi Rib Eye Steak and Wasabi Mashed Potatoes sound delicious – I’ll be trying them out sometime soon. Back Issues of Chile Pepper Magazine are available here.

That must be hot.
Wow this is a great article. I never knew what that green stuff “really’ was. I actually thought it was somthing from Gostbusters or somthing (then again getting sushi in some places in Mahattan – Lord knows what you’re eating). I got to go down and see if we can get some fresh Watsabi
Fresh wasabi rhizomes are also available at http://www.realwasabi.com.
Thanks Nick. Now I have to go and find some real Wasabi and do a comparsion myself. I can eat a ton of the fake stuff now let’s see what the real stuff is made of.
Even so called 100% Pure Wasabi paste has some additives to keep the product stable. This is true even if the product is frozen. Why is this? Because as soon as you damage the cell walls of the wasabi the active ingredients start to react with the water that is in the wasabi and the air. These means all the goodies quickly evaporate unless you add vinegar or oil or lemon juice. The only way to get 100% Pure Wasabia japonica is to dry the wasabi without using heat before processing it. New Zealand Wasabi Limited does just that, so our product does not have any additives of any kind. It is 100% Pure Wasabia japonica, which only needs the addition of cold water to reactivate the pleasant rush you get from eating the plant straight out of the stream. That flavour and taste is amazing. Even being out of the water for a day reduces that flavour.
