What is Wasabi?
Traditionally grated fresh from its pale green rhizome, wasabi offers a uniquely sharp yet elegant pungency, prized as much for its aroma as for its heat. Beyond raw fish, it appears in sauces, dressings, marinades, and modern applications such as pasta dishes and savoury snacks. Genuine wasabi is exceptionally rare outside Japan, as the plant demands precise growing conditions; most commercial “wasabi” products are based on horseradish. Historically, its natural antibacterial compounds made it a practical and flavourful partner to raw seafood.

Bright and pungent with a horseradish-like character, wasabi delivers a cooling, sinus-clearing heat that dissipates quickly, leaving behind a subtle sweetness and allowing other flavours to shine.
Where Does Wasabi Come From?
Native to the cool mountain streams of Japan, wasabi thrives in shaded environments with flowing water. Limited cultivation also exists in Korea, Taiwan, and select regions of the United States, though production remains challenging and small-scale.
