Medovik (medovnik)

Instructions

1. Melt the butter with the honey and sugar over low heat, then let it cool slightly.
2. Add the eggs one at a time, then the baking soda slaked with vinegar and a pinch of salt.
3. Work in the sifted flour until you get a soft dough. Divide it into 6 to 8 balls.
4. Preheat the oven to 180 °C. Roll each ball into a very thin disc and bake them 4 to 5 minutes on a tray, until golden.
5. While they bake, prepare the cream by whisking the sour cream with the condensed milk and icing sugar.
6. Stack the discs, spreading cream between each layer, and keep the pastry trimmings crumbled for the top.
7. Cover the cake with crumbs and chopped walnuts, then refrigerate for at least 6 hours before serving.
