500 g of flour
150 g of margarine
3/4 cup of sour cream (a thicker, tangier version of sour cream common in Eastern European cuisine)
2 eggs
30 g of yeast
1 tbsp of milk
1 tbsp of caraway seeds
1 tsp of coarse salt
Start by rubbing the margarine into the flour. Then, add the yeast that has been dissolved in the milk, one whole egg, the egg yolk, and the sour cream. Knead the dough until smooth. Roll out a thin log from the dough and cut it into finger-sized pieces, about 7-10 cm long. Place the pieces on a greased baking sheet, cover them with a towel, and set them in a warm place to rise. Once they have puffed up, brush them with egg white, sprinkle with the caraway seeds mixed with coarse salt, and bake in a preheated oven at 240°C (about 465°F) for 10-15 minutes. Your fingers are ready!
