Real Franzbrötchen with Puff Pastry

Day 1 evening or in the morning if you wish to serve them the following day

If the butter for the butter layer is not at room temperature yet, take out of the fridge. Peel potatoes, cut in small pieces and boil in hot water, drain, mash and measure 80 grams. For the dough combine mashed potatoes and all ingredients except for the cold butter in a large mixing bowl and knead on lowest speed for about seven minutes. Cut the cold butter in slices and add to the dough. Knead for three minutes. Chill dough covered in the fridge for 8-12 hours.

For the butter layer beat the soft butter with the flour for about two minutes. Then spoon the butter onto a parchment paper and create a square of about 25cmx25cm (see pictures). Also chill in the fridge overnight.

Day 2

Roll out dough on a lightly floured surface into a rectangle of 25cmx50cm. Place the chilled butter square in the middle of the dough and wrap from both sides with the dough (see pictures). Roll out dough again, creating again a rectangle of 35cmx60cm. Once done, fold dough in thirds like you would fold a business letter and then roll out again into a rectangle of 35cmx60cm. If your dough still is cold enough, repeat this procedure two more times. My dough had to be chilled between 15-30min before I could continue. After the foruth "turn" chill fridge for half an hour in the fridge.

Roll out dough into a rectangle of 30x60cm and brush with melted butter of the filling. Generously sprinkle with sugar and cinnamon. Roll into a log starting at the long side. Cut log into about 12 equally sized pices. Press down a wooden handle into the middle of each piece (see pictures). Cover these rolls and let rise for about three hours at room temperature. Then transfer to the fridge overnight.

Day 3 in the morning

Preheat oven to 220 degrees Celsius and place rolls on a baking sheet lined with parchment paper. Bake for about ten minutes and reduce oven temperature to 180 degrees. Bake for five more minutes or until golden. Serve warm for breakfast.
