The recipe for eggs in mustard sauce comes from Magdalena Rilke (24 March 1864-10 February 1929), originally from Lower Silesia, who married Ernst Hahn in her second marriage and founded the cookery book publisher Mary Hahn with him in Frankfurt am Main. The illustrated cookery book for simple and refined cuisine won many awards and was so popular that it appeared in countless editions. The mustard sauce is simple and sophisticated at the same time. It is a roux made with stock, mustard, apple cider vinegar and lemon slices.
