Knowra Wasabi Wasabi Wasabi is a pungent Japanese condiment made by grating the rhizome of Wasabia japonica. Its sharp heat comes mainly from volatile compounds that quickly fade after grating.
Wasabia japonica : A Japanese plant in the cabbage family whose rhizome is grated to make traditional wasabi. Its rhizome is the source of the condiment.
Izu Peninsula : A mountainous peninsula in Shizuoka Prefecture, Japan, known for traditional wasabi cultivation. Its spring-fed valleys became a major center of wasabi production.
Sushi : A Japanese dish of vinegared rice, often served with seafood, vegetables, or other toppings. Wasabi is commonly served alongside sushi for pungency and flavor contrast.
Horseradish : A pungent root vegetable in the mustard family, commonly used as a condiment and wasabi substitute. Its strong flavor resembles wasabi, and it is a frequent ingredient in imitation wasabi.
Sinigrin : A glucosinolate in wasabi and other Brassica plants that can be converted into pungent compounds. Tissue damage brings this precursor into contact with the enzyme that produces wasabi’s sharpness.
Shizuoka Prefecture : A prefecture on Japan’s Pacific coast, with a long history of commercial wasabi cultivation. Wasabi farming in its mountain streams helped establish the crop’s modern reputation.
Sashimi : A Japanese dish of thinly sliced raw seafood or meat, served without rice. Wasabi is traditionally paired with sashimi, often with soy sauce.
Mustard : A pungent condiment made from seeds or leaves of plants in the mustard family. Its sharpness also comes from glucosinolate breakdown, but its ingredients and flavor differ.
Myrosinase : An enzyme that hydrolyzes glucosinolates into products including pungent isothiocyanates. Grating mixes myrosinase with glucosinolates in wasabi tissue.
Wasabi cultivation : The farming of Wasabia japonica, often in cool, shaded, flowing-water beds or on upland fields. Its demanding growing conditions shape the supply of fresh rhizomes.
