Brynz cake

Whisk the eggs with salt, add the flour, knead the uncool dough and divide it into 6-8 pieces. Roll each piece subtly into a cake. Boil the water in a wide, low saucepan. One at a time, lower the cake into boiling water for 1-2 minutes, then cool in cold water and put it on the desktop. Grate the chilled butter on each cake, put an even layer of brynza grated on a fine grater on top. Fold the cake into the cake, rub only the butter on the top cake. Put the cake in the preheated oven over a small heat for 30-40 minutes. Serve hot.
