Tarragon has a bitter, pepper-like, aniseed palate. This is mainly known from sauces like bearnaise, but is also used in vinaigrettes and mustard. The flowers and leafs can be used for making tea which improves the kidney function.
Tarragon is a part of the "Fines herbs" which is a herb melange often used for flavouring soups, eggs, and butter.
