French and Russian are two types of Tarragon. We select French tarragon because it has a deep green color. Russian tarragon is often grayer with somewhat brownish leaves. In addition, French tarragon has a wonderful aroma which is slightly licorice. When used in cooking, it absolutely perfumes the house.Tarragon is used to flavor egg dishes and omelets, is an essential in Fines Herbes and Sauce Bƃ¶?arnaise. It is good with roasted meats, fish and especially good with chicken. One of the easiest and most elegant of recipes is Tarragon Chicken. This classic dish calls for stuffing the cavity with handfuls of tarragon and basting with lemon and butter.
