This lemon cold dish recipe comes from the household of my dear neighbour Helma. The fourth edition of the Dr Oetker school cookbook from 1929 was still on the kitchen shelf in her parents' kitchen when she gave it to me as a present. What originally began in 1891 with small recipe booklets as a marketing strategy of the Bielefeld entrepreneur Dr August Oetker, continued from around 1910 with his cooking and baking recipes in book form right up to the present day and is therefore one of the classic cookery books. This school cookery book was written by the home economics teacher Emilie Henneking and could be purchased for 30 pfennigs.
