Proteins separated from the yolks. To the yolks, add 150 g of sugar. Grind white. Mix with sour cream, soft butter, baking powder and flour. Put the zest of one lemon.

Get a sticky dough. In the original, this they divided the dough in two and baked on a square baking tray with two layers. This would have very subtly put the dough, which for me proved to be difficult. The dough sticks to the hands and does not want an even layer to give a sheet. So stick frying pan, and the cakes turned out thicker than the original, but the taste is not affected. Happened three layers. Bake at temp. 170*C for 15-20 minutes. Depends on the oven.

Here is another raw cake.

While the cakes baked, I prepared the filling. To do this, two apples cooked mashed potatoes (this is not in the original). Apples have softened the acid of lemon. Two large lemon scalded with boiling water or boil for a bit. Cut, remove pits and grind in a blender or grinder. Add 150 g of sugar, however, see a good choice.

Cakes generously fluff filling, it will be a lot and it is well absorbed, making the cake incredibly soft and delicious.

Proteins vzbit to hard peaks, adding 50 g of sugar. Grease the cake top and sides.

Put in the oven until a little Browning.

So it turns out.
