Let’s start with making the dough. In warm milk, dissolve salt, vanillin and yeast. Leave it on for 15 minutes. Meanwhile, beat the eggs with sugar to a white air mass. Melt the margarine. Mix everything and add the sifted flour. Knead the dough. It will be sticky, but you don’t need to add more flour. Leave the dough to rise in a warm place for 1.5 hours.
