Peeling from 1 lemon * * Is "Zetst" the correct word? Mix all dough ingredients together and let them stay for half an hour. Mix filling ingredients on a pan over fire till it gets thick. Remove heat and add the lemon peeling. Thin the dough on a floured surface to a thin layer. Cut with a glass round portions from the dough, put some filling on each round and fold the dough to the traditional triangular form. Bake in a preheated oven at 180 grades Celsius for about half an hour. Optionally smear some egg-yolk on the cookies a few minutes before baking is finished to add some glaze.
