Fresh wasabi versus store wasabi paste shocking truth about what you actually eat at restaurants

When you enjoy sushi or sashimi at a restaurant, the wasabi served is most likely not the real thing. Fresh wasabi, derived from the wasabia japonica plant, is a rare and expensive delicacy, often costing upwards of $100 per pound. However, what you typically encounter in restaurants is a paste made from horseradish, mustard, and food coloring, marketed as wasabi. This imitation is much cheaper to produce and easier to store, leading to its widespread use.

The primary ingredient in most store-bought wasabi pastes is horseradish, which has a similar pungency but lacks the depth of flavor that authentic wasabi offers. Additionally, many of these products contain artificial coloring to mimic the vibrant green hue of fresh wasabi, misleading diners into thinking they are enjoying the genuine article. In fact, some studies have shown that 90% of products labeled as wasabi in stores and restaurants contain little to no actual wasabi.

If you're keen on experiencing real wasabi, look for specialty sushi restaurants that advertise fresh wasabi on their menu. These establishments often take pride in offering an authentic culinary experience and may even grate the wasabi root fresh at your table. You can also find fresh wasabi in specialty Asian markets or online, where it might be sold as whole roots or freshly grated.

When trying fresh wasabi, it's important to note that it should be prepared just before consumption. Grating the wasabi root releases its volatile compounds, which provide the characteristic heat. Unlike its horseradish counterpart, fresh wasabi's flavor is best enjoyed immediately after grating, as it loses potency quickly.

In summary, the shocking truth is that most of what you encounter as wasabi in restaurants is not the real deal, but rather a horseradish-based imitation. If you're looking to indulge in the authentic experience, seek out establishments that serve fresh wasabi or purchase it yourself from reputable sources.
