Put 1100 g flour, 2 teaspoons salt, sugar, butter and eggs into a large mixing bowl. Warm the milk lukewarm. Crumble yeast into it and dissolve it. Add yeast milk and quark to the flour mixture and knead everything with the dough hooks of the mixer to a smooth dough. Cover and leave to rise in a warm place for about 1 hour.
Knead the dough on a well floured work surface (the dough is quite sticky). With well floured hands form about 24 rolls and spread them on two baking trays lined with baking paper. Cover them and let them rise again in a warm place for about 1 hour.
Bake rolls sheet by sheet in a preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer) for approx. 20 minutes. Let cool off.
