Sift the flour, add the powdered sugar, softened butter, cheese, yolk, zest (optional, I added), and knead the dough.

Send the dough in the fridge for an hour.

Roll out chilled dough is 4-5 mm thick and cut out circles. Half circles make a hole in the middle. I have a large diameter - 7 cm, the smallest - 3 cm (convenient to take the Cup and the lid from a plastic bottle, if nothing is there).

Circles to greased and proteiny parchment cookie sheet, spread the slices with protein, top to put the rings. Cookies again to lubricate the protein and sprinkle with almonds. I got 10 pieces Bake in preheated oven at 180 degrees for about 20 minutes - until Golden brown. Jam to spread in warm cookies - making it easier to level. I used homemade jam from a red currant (so the zest and didn't put acid enough).
