Chives are a member of the onion family and have a mild onion flavor. They are a really versatile herb with lots of uses â€” garnishing, in salads, in vegetable and egg dishes, with fish, chicken and mild flavoured meats. Chives should be added to a dish just before serving because too much heat can destroy the flavor. Garlic chives are also available. The leaves of garlic chives are flat, not hollow and circular as in standard chives, and they have the distinctive taste of garlic.
