Wakame, Undaria pinnatifida, is a species of edible seaweed, a type of marine algae, and a sea vegetable. It has subtly sweet, but distinctive and strong flavor and texture. It is most often served in soups and salads.Wakame is a delicate, lightly sweet seaweed often used raw and rehydrated in salads and miso soup. Because of its silky, satiny texture, it is important to pair wakame with ingredients that have some crunch or chew, like cucumbers in a Japanese sunomono salad, for better balance. Add some to massaged kale salads along with avocado, toasted sesame seeds, and lightly pickled red cabbage or kraut. Or try using it in sesame oil–flavored cold noodle salads along with toasted peanuts.
