From Japan, wasabi is a root that’s related to mustard. Use it sparingly at first, or wowza! The hot, pungent flavor is similar to horseradish, but the heat vanishes quickly, leaving a slightly sweet taste. You might have seen it served with sushi, sashimi, or noodles. If you’re looking for some zing in your life, look for wasabi-flavored nuts, chips, dressings, cheese, or dried peas.
