Overview
Surrogates
Wasabi favours growing conditions that restrict its wide cultivation – among other things, it is quite intolerant of direct sunlight, requires an air temperature between 8 and 20 °C (46 and 68 °F), and prefers high humidity in summer. This makes fully satisfying commercial demand impossible for growers, which makes wasabi quite expensive. Therefore, outside Japan, finding real wasabi plants is rare.
Taxonomy
The wasabi plant is native to Japan and the Russian Far East, also the Korean Peninsula. Siebold named Cochlearia (?) wasabi in 1830, noting its use pro condimento or "as a condiment"; however, this is a nomen nudum, and the synonym Eutrema wasabi, published by Maximovich in 1873, is thus an illegitimate name. The wasabi plant was first described by Miquel in 1866, as Lunaria (?) japonica, from the type collected by Siebold in Japan, though the precise type locality was not rec…
Uses
Wasabi is generally sold either as a rhizome or stem, which must be very finely grated before use, as dried powder, or as a ready-to-use paste in tubes similar to toothpaste tubes.
The part used for wasabi paste is variously characterised as a rhizome, a stem, or the "rhizome plus the base part of the stem".
Chemistry
The chemical in wasabi that provides for its initial pungency is the volatile compound allyl isothiocyanate, which is produced by hydrolysis of natural thioglucosides (conjugates of the sugar glucose, and sulfur-containing organic compounds); the hydrolysis reaction is catalyzed by myrosinase and occurs when the enzyme is released on cell rupture caused by maceration – e.g., grating – of the plant. The same compound is responsible for the pungency of horseradish and …
Nutritional information
Wasabi is normally consumed in such small quantities that its nutritional value is negligible. The major constituents of raw wasabi root are carbohydrates (23.5%), water (69.1%), fat (0.63%), and protein (4.8%).
Cultivation
Few places are suitable for large-scale wasabi cultivation, which is difficult even in ideal conditions. In Japan, wasabi is cultivated mainly in these regions:
• Izu Peninsula in Shizuoka Prefecture ("Traditional Wasabi Cultivation in Shizuoka, Japan" is a Globally and Japanese Nationally Important Agricultural Heritage System )
Preparation
Wasabi is often grated with a metal oroshigane, but some prefer to use a more traditional tool made of dried sharkskin (fine skin on one side; coarse skin on the other). A hand-made grater with irregular shark teeth can also be used. If a shark-skin grater is unavailable, a ceramic cheese grater can be an acceptable substitute.
