Chives are a popular herb used in European cookery. They have long, thin green blades that are hollow inside. They have a mild, grassy flavour similar to baby spring onions or young leeks. Use chive greens to flavor salads, egg dishes, baked potatoes, fish, soups, and more.Chive leaves add a mild fresh onion taste and also enhance the natural flavors of the food to which they are added. You can also add fresh chive to softened cream cheese or butter for a delightful bread or bagel spread.
