RUB the yolks with 0.5 tbsp. sugar until white in color (I rubbed it with takuseshi)

Mashed yolks add buttermilk (sour milk),salt,soda (to repay), flour. Knead the dough(not cool)

Roll the dough out to a thickness of 3 cm and cut out circles with a diameter of 5 cm Put the slices on a sheet (I covered with parchment paper) are very close to each other that they went only up (get a page). Put in the oven (200 C) for 45 minutes (ovens are all different, so try the readiness of a match)

Take out the cakes from the oven and let them cool slightly.

Meanwhile, whisk into a thick mass 3 protein with 3 cups of sugar.

Warm gingerbread dipped completely in the beaten egg white. To put on the table to dry. After the cakes are dry, put them into a saucepan and cover with a lid, so they were soft. BON APPETIT!!!
