Ruccola or Roquette originates from South-America and Southern-Europe, where it has been bred for ages. Around 1981, ruccola was introduced in Holland by the company Tubbergen.
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.
