Layered buns with sour milk

Ingredients:

• 1 and 3/4 cups bread flour
• 1 3/4 cups cake flour, plus extra for work
• 2.5 tbsp baking powder
• 1/4 cup sugar
• 1.5 tsp salt
• 3/4 cup + 2 tbsp. shortening
• 2 large eggs + 1 beaten egg for brushing
• 1 cup of sour milk or milk

Preparation:

1. Preheat oven to 175°C. Grease a baking sheet with butter.
2. In a large bowl, combine the bread flour, cake flour, baking powder, sugar, and salt. Fold in the shortening with your fingers. Beat the eggs with the sour milk, then fold into the flour mixture with a fork, and knead into a loose dough.
3. Place the dough on a lightly floured work surface and roll it out to a thickness of 0.5 cm. Using a glass or a round cookie cutter with a diameter of 8 cm, cut out round buns, re-rolling the scraps if necessary. Transfer to the prepared baking sheet. Brush with beaten egg.
4. Bake until golden brown, 18-20 minutes. Transfer to a wire rack and let cool slightly. Serve warm.
