Make a kneading dough from the dough ingredients and chill the dough for about 1 hour.
Roll out in portions and cut out hearts. In the halves of the hearts, cut out hearts again with a smaller shape. Mix the egg yolk with the milk and use it to brush the edges of the hearts cut out inside. Place all hearts on a baking sheet lined with baking paper.
Bake in a preheated oven at 180 ° C for about 10 minutes. Then let the cookies cool down.
Let the currant jelly boil down while stirring (but it is not absolutely necessary) and use it to brush the hearts that have not been cut out. Put both parts together.
