Most Wasabi Paste Isn’t Real Wasabi

If you enjoy wasabi when you’re at a sushi restaurant, you might be surprised to find out that what you’re actually eating probably isn’t wasabi at all. That’s because real wasabi is expensive. The green paste is instead likely horseradish, which is in the same family as wasabi like other “Brassicaceae,” such as cabbage, broccoli, cauliflower, radish, mustard, and watercress.
