Chervil or French parsley is used to season poultry, seafood, young spring vegetables, soups, and sauces. More delicate than parsley, it has a faint taste of liquorice. This herb is essential in many French dishes. Unlike its cousins, parsley, and cilantro, chervil isn't easy to find at most markets other than specialty stores. As a spring herb, chervil will be available at different times depending on the local climate. You can grow chervil yourself in an herb garden. It can be grown in a small pot on your windowsill or you can plant it in a garden that gets a mixture of sun and shade.
