 Frankfurter Kranz is considered a reminiscence of Frankfurt as the coronation city of the German emperors.Its round shape and the sheath of brittle are intended to represent a golden crown, the cherries should remind of rubies.After World War II, in the absence of butter, the surface of the cake was often coated with Kogel mogel (sweetened egg yolk paste), and other types of decoration may involve dots made from (more) buttercream or cocktail cherries.
