Grüne Soße (Green sauce) is a traditional local delicacy of Frankfurt. It is rumored that it was the favourite food of Goethe however there is no evidence to support this claim. A traditional way to serve Grüne Soße is with hard boiled eggs and pan-fried potatoes.
The sauce which is made up of 7 herbs is usually served cold. These are the herbs that MUST be used – parsley, chives, cress, sorrel, chervil, borrage, and salad burne. This is a truly local dish as most of the herbs used are said to originate from Frankfurt’s neighborhood. One can only sell the sauce as Frankfurt Grüne Soße if more than 60% of the herbs are from Frankfurt. No kidding!
