Key facts and history

Siebold named Cochlearia wasabi in 1830, noting its use as a condiment, but this was a nomen nudum.[2] The chemical allyl isothiocyanate provides wasabi's initial pungency and is produced when the plant cells are ruptured by grating.[3] Miquel provided the first botanical description of the wasabi plant in 1866, naming it Lunaria japonica based on a specimen collected by Siebold in Japan.[2] The plant was moved to the genus Eutrema by Koidzumi in 1930, resulting in the accepted name Eutrema japonicum.[4]

Blooming from late winter to early spring, wasabi's flowers grow in clusters on long stems.[5] Vernalization, triggered by cold temperatures, causes wasabi flowering to start in January in Japan.[6] For grating the fresh rhizome into a paste, traditional practice uses coarse sharkskin, whereas modern kitchens employ metal graters.[7] To prevent fresh wasabi paste from quickly losing its flavor when exposed to air, high-end establishments grate it only at the moment of serving.[7]

A team from Japan received the 2011 Ig Nobel Prize in Chemistry for figuring out the optimal concentration of airborne wasabi to rouse sleeping individuals during an emergency.[8]

What the cited sources add

The North Carolina Extension Gardener Plant Toolbox notes that wasabi is high in vitamin C and also contains vitamin A and iron.[9] The same source states that wasabi is studied for medicinal uses including anti-inflammatory and antibacterial properties.[9] The Banjo Foods account explains that hon-wasabi is classified as sawa-wasabi (stream-bed grown) or hatake-wasabi (field grown).[10] Sawa-wasabi grows wild in cold, clear waters of mountain valleys and is cultivated in similar conditions.[10]

The Izu district in Shizuoka Prefecture is the largest production area for hon-wasabi in Japan.[10]
