Pansies can have a mild, fresh flavor or a more prominent wintergreen taste, depending on the variety and on how much of the flower you eat (a whole flower tastes stronger than the petals alone). Eat only pansies that are grown organically, without chemical pesticides; this rules out almost everything from florists, garden centers, and nurseries. If you plan to eat pansies, it's a good idea either to grow them yourself or to order them from an edible-flower source. Use the pansies to garnish cocktails, soups, and desserts.
