The wasabi sushi restaurants serve is pretty much never actual wasabi

Think you like wasabi? Think again. The little green balls that sting nostrils and line sushi platters around the world are very rarely what their name suggests. What sushi restaurants actually serve alongside spicy tuna rolls is a horseradish-based concoction that is injected with green food coloring, infused with various types of mustard, and, often even, a bunch of other chemicals.
