Work the flour, baking powder, salt, sugar and butter in small pieces into a crumbly mass. Then pour 375 ml of beer and make a soft batter.
Place the dough on a lightly floured work surface and knead until smooth, adding more flour if necessary. Shape the dough into four balls, place on a greased baking sheet and flatten a little. Then brush with a little water and cut into the surface with a knife. Sprinkle with caraway seeds to taste.
Bake in the preheated oven at 210 ° C for at least 10 minutes (usually a little longer). Makes 4 rolls.
