What is "eierschecke"

Eierschecke is a confectionery speciality from Saxony and Thuringia. It is a sheet cake made of yeast dough topped with apple, quark (curd) and poppy seeds and parts of it are covered with a glaze made of cream, whole egg, sugar and flour for thickening.[1] The term originates from a piece of men's clothing in the 14th century which was called Schecke and was made up of a medium-length tunic with a very tight waistline and was worn with a Dusing, a hip belt. After this "tripartite garment" (upper part, belt, lower part) the cake was named.
