When people think of Japan, sushi and sashimi often come to mind.
A crucial element that complements these dishes is wasabi.
Known for its unique flavor and pungency, wasabi is a staple in Japanese cuisine.
In this article, we delve into the depths of Japanese wasabi and explore its captivating allure.
What is Wasabi?
Wasabi (山葵) is a plant belonging to the Brassicaceae family, and its rhizome is grated for use.
Wasabi is famous for its distinctive spiciness, which is felt as a sharp, nasal sensation.
Unlike other spices, wasabi’s heat is instantaneous and doesn’t linger.
The Difference Between Japanese Wasabi and Western Wasabi
Often confused with each other, Japanese wasabi (hon-wasabi) and Western wasabi (horseradish) are different plants.
Western wasabi is widely used in Europe and is known for its stronger pungency and whitish color compared to hon-wasabi.
Japanese hon-wasabi is green and offers a unique flavor with a delicate spiciness.
Both have their own culinary uses, but hon-wasabi is indispensable in Japanese cuisine.
The Cultural History of Wasabi
Wasabi has long been a part of Japanese food culture.
There are records of its use as a medicinal plant as far back as the Nara period (8th century).
By the Heian period (9th century), it began to be used as a food ingredient.
During the Edo period (17th century), sushi became widely popular, and wasabi established itself as a common condiment for sushi.
Over time, wasabi evolved alongside Japanese history and has now become an essential element of Japanese cuisine, beloved worldwide.
