Fastenwähe is a type of small Swiss bread, carnival treat, and snack originating from Basel. The dough is usually made with a combination of flour, yeast, salt, sugar, milk, eggs, caraway seeds, and butter. Once the dough has rested and doubled in size, it's divided and shaped into ovals.
A knife is used to cut four slits into each piece of dough, which is then carefully stretched in order to create a shape that's similar to a cross in the middle of the dough. The dough is brushed with beaten egg yolks, sprinkled with caraway seeds, and baked until golden.
