Mix the yeast with the lukewarm buttermilk, syrup and the salt and wait until it starts to go, about 10-30 minutes.
Then process the flour and butter together and knead until a smooth dough is formed. Cover and let rise for about 40 minutes at room temperature and form about 10 rolls.
Place this on a baking sheet and let rise, covered, for 30 minutes and then brush with lukewarm milk.
Bake in the preheated oven at 200 ° C for 25 minutes.
Spray some water on the rolls before, during and afterwards.
