Melt the butter with the honey in a water bath. Curd RUB through a sieve, mix with honey mixture, egg yolks, zest, cinnamon and baking powder. Add the flour and knead the dough.

Roll the dough into a thin layer and cut into squares with sides 8 cm.

In the center of each square put 1.5 tbsp of jam, to pull the edge to the center and stung them, leaving long "tails".

Preheat the oven to 190°C. Put the cakes in butter and sprinkle with a parchment baking sheet, brush with protein. Bake 20 min. There is such a trick: in open and semi-open pies not to cause a jam or marmalade too thick. Not thick layer of jam in the baking time will are dried, thickens from the heat of the oven and will not flow out. If there is any doubt, in a jam, you can add starch (corn or potato).
