Just because your wasabi is aggressively spicy doesn't mean it's real; in fact, most of the wasabi in Western supermarkets is regular horseradish dyed green. Popular Japanese brand Kameya makes its product with true wasabi, or Japanese horseradish, which is incredibly rare because it only grows naturally along stream beds in Japan's mountainous regions. Beneath its sinus-clearing spice, wasabi has delicate earthy and vegetal notes that give the paste a refreshing, aromatic quality. Beyond sushi, add a dab to vinaigrettes or teriyaki glazes for fish, or try a small amount in your ham and brie sandwich or on your cheese platter—there's little its spicy herbal goodness can't improve!
