Sushi Sonic 100% Real Powdered Wasabi, 1.5-Ounce Jars (Pack of 3)
$18.64
I've eaten sushi my whole life, including in Japan. And this wasabi isn't what I'm used to. It's not that it tastes bad, but it isn't as piquant as I like. It doesn't make your noise burn and open-up. Personally, I like that sensation. This product doesn't impart much flavor or sensation at all. It is natural though, as well as only 100% wasabi japonica. Because there are no added coloring agents, it doesn't give the color that most are used to from wasabi; personally, i don't mind that.
So overall, this product isn't terrible. If you really want a product without artificial ingredients, you may like this or Sushi Sonic's 45% wasabi powder (which I haven't tried). It may also be enjoyed by someone who wants a less pungent wasabi. Or maybe you just want to try what pure wasabi tastes like. . . I will stick with other brands that sell more affordable wasabi powder (and I do recommend buying wasabi in powder-form as it keeps longer this way).

Neri Wasabi Tube 1.52 Oz.
$2.99
WASABI! The Japanese horseradish found in Sushi Bars and Restaurants, this is Hot Stuff! It adds that special "kick" to your sushi or sashimi (raw fish) and also makes a wonderful sauce for any kind of fish, raw, cooked or otherwise (especially batter fried!) when mixed with mayonaisse or another great sauce for potstickers when mixed with soy sauce.

Wasabi Peas 5 lbs. (80 oz.)
$21.95
this one is my favorite out of most wasabi peas I tried. perfect heat and salty taste. the price is outstanding too.

S&B - Wasabi in Plastic Tube 1.52 Oz.
$2.29
First thing to know about this product is that it isn't actually wasabi. Actual wasabi, known as hon-wasabi, comes from that lovely sinus-clearing wasabi plant, and should be grated right from the root much like ginger. It can be found in tube form as well, but that is much rarer.

This little squeeze-tube, like the powder stuff, is just regular horseradish, mustard seed and some food coloring. It contains 0% of the actual wasabi plant, and the flavor is different from hon-wasabi, although similar.

But it still works. For most recipes, using the expensive hon-wasabi would be a waste of money, and this imitation does the job just fine. I personally keep both kinds, hon-wasabi for when I am using it directly for sashimi and a tube of the old faithful S&B for when I want to make wasabi-flavored dishes.

It is too bad that it is so expensive, because this tube would go for about a dollar a pop in Japan, but that is the price of imports eh?
