Wasabi
Wasabi is a Japanese condiment made from the grated rhizome of a Brassicaceae plant, typically associated with sushi and sashimi.
Wasabi is a Japanese condiment made from the grated rhizome of a plant in the mustard family. It is known for its sharp, pungent heat and is commonly served with sushi and sashimi.
What it is
Wasabi refers both to the plant *Eutrema japonicum* and to the green paste made from its rhizome. It belongs to the Brassicaceae family, alongside horseradish and mustard. Authentic wasabi is native to Japan, the Russian Far East, and the Korean Peninsula.
Why it matters
Wasabi is a traditional condiment for sushi and sashimi, valued for its nasal-clearing pungency. However, most commercial products sold as wasabi in Canada and elsewhere contain little or no real wasabi, instead using coloured horseradish. This matters for authenticity and flavour.
Key details
The heat of wasabi is volatile and fades quickly after grating. It irritates the nose more than the tongue, unlike chilli peppers. Cultivation is limited because the plant requires specific conditions, such as cool, running water and shade.
