Frankfurter Grüne Soße

Frankfurter Grüne Soße is a famous cold herb sauce from Frankfurt, consisting of sour cream, spices, and herbs. Traditionally, there should be seven herbs in the sauce, and 70% of them should have been grown in Frankfurt. These seven herbs are borage, chervil, garden cress, parsley, salad burnet, sorrel, and chives. The sauce is so well-known that there is even a Grüne Soße monument in Frankfurt-Oberrad. The monument consists of seven greenhouses, each one representing a different herb used in the sauce. It is still unknown whether the French immigrants or Italian traders brought the recipe to Frankfurt, since green sauces were known for centuries in those countries. There's also a very popular myth about the green sauce being Goethe's favorite dish, and according to it, it was invented by his mother. Although there is no evidence for the popular myth, it is a fact that the first recipe for the sauce was found in an 1860 cookbook written by Wilhelmine Rührig. Today, the sauce is commonly served with boiled eggs and potatoes, fish, or Tafelspitz.
