For cranberry pockets, first sift flour with baking powder and crumble with the cold butter. Add the curd cheese and salt and quickly knead into a dough. Let it rest in the refrigerator for at least 1 hour.
Then roll out the dough to a thickness of 2-3 mm and divide into squares of about 10 cm. Brush the edges with egg white and place 1 tsp of cranberry jam in the center of each. Fold the squares together and press the edges firmly. Brush the outside with egg white.
Cover a baking tray with baking paper and bake the pastries in the preheated oven at 200 °C for about 20 minutes until they are golden brown.
Mix the powdered sugar with the vanilla sugar and sprinkle over the hot cranberry pockets.
