For savory cheese fritters, bring milk to a boil with 40 g butter and salt, then stir in flour with wooden spoon. Stir constantly until the dough separates from the utensils and cooking spoon.
Transfer the mixture to a bowl, add 30 grams of butter, eggs, Parmesan cheese and cayenne pepper to make a firmer dough.
Stir the Emmental cheese into the dough. Then pour the dough into a pastry bag with a large nozzle and pipe walnut-sized doughnuts onto a baking tray lined with baking paper.
Brush the piquant cheese doughnuts with beaten egg and bake in a preheated oven at 190 degrees Celsius for 20 minutes.
Pikante Käsekrapferl are a spicy pastry that is best served while still warm.
