Parsley is an essential herb and can even be used as a salad leaf. I personally use large quantities parsley which goes well with fish, butter sauces and more mild sauces, It is excellent sauteed with garlic, lemon juice as a sauce, and will hold its own in the kitchen against all most all other herbs. Parsley is one of the "fines herbes" of French cuisine, which also include tarragon, chervil and chives. It has a strong place in almost all European, Central European, American and South American cuisines.
