Jam cakes

Sow the oil with flour, add the boiled yolk, strained through a sieve and mixed with sugar, add the vinegar and mix the dough. Roll the dough into a layer, like dumplings, cut out circles with a glass and put it on an oil-lubricated baking sheet. Bake in a hot oven (200-220 ° C) for 20-25 minutes. Grease the baked cakes with jam and fold in pairs. The cakes can be topped with whipped protein with sugar (1 protein + 50g sugar), put half a nut on top and put in the oven to dry the protein.
