Frankfurt's cold green sauce blends exactly seven herbs with soured cream, poured over halved boiled eggs and potatoes. It is a main course here, not a condiment, and the city argues about every family's ratio.

Grüne Soße belongs to Frankfurt the way pesto belongs to Genoa. The canonical seven herbs are borage, sorrel, garden cress, chervil, chives, parsley and salad burnet, most of them grown in the Oberrad district, which styles itself the city's herb garden. Legend ties the sauce to Goethe's mother, and the city now stages a week-long Grüne Soße Festival each May where restaurant versions compete on the Roßmarkt. Season traditionally opens around Maundy Thursday, when the first bundled herb packets appear at the markets.
