With its fragrant and feathery green leaves, dill is a staple in a variety of recipes, accentuating the flavor of soups, salads, fish, poultry, and of course, pickles. A member of the parsley family, dill is native to the Mediterranean and West Asia regions and dates back as far as 3000 B.C. Dill leaves can be used as a culinary herb, while dill seeds are often used as a spice, with a flavor similar to caraway.
