For the nut buns, first prepare the nut filling. Bring the milk slowly to the boil and remove from the heat. Stir in the grated nuts and flavor with sugar, vanilla sugar, honey, a good pinch of cinnamon and a dash of rum. Add the soaked raisins to taste. Allow the mixture to cool.
Roll out puff pastry or risen yeast dough into a rectangle on a floured work surface. Spread nut mixture on the dough and roll up from the wide side to form a roulade. Cut into slices about 2 fingers wide, place on a baking sheet lined with parchment paper and gently flatten each slice. While doing this, press the end of the dough down well or tuck it under the scroll.
Brush with beaten egg and bake in a preheated oven at 180 °C for 15-20 minutes, depending on the dough. Lift out the nut buns and coat with hot jam or sugar glaze as desired.
