For the potato rolls, peel the potatoes, cooked the day before if possible, grate, mix with the flour. Mix the yeast with the milk, stir a little and pour on the flour-peanut mixture.
Add salt, eggs and butter and work everything into a smooth dough. Cover and let rise in a warm place for about 30 minutes. Knead again, roll out on a floured surface.
Cut out round discs with a glass and place them on a baking sheet lined with baking paper. Brush with beaten yolk and let rise, covered, for another 20 minutes.
Then bake in the preheated oven at 220 °C for about 15-20 minutes.
Preparation Tip:
If you like, sprinkle the potato crackers with caraway seeds or sesame seeds before baking.
