Put milk powder in a bowl and knead with clarified butter flakes to fine crumbles. Add flour, baking powder, cardamom and about 100 ml cold water and knead to a very firm dough.
Wrap the dough in foil or a damp cloth and let it rest for at least 3 hours. Then tear the dough into pieces and grind them on a floured board. Sprinkle with a little water and form into walnut-sized balls.
Heat the fat in a frying pan or deep fryer to 180 °C and fry the milk pastry balls in it until golden brown, turning them carefully from time to time. Take them out and let them drip off on kitchen paper.
Meanwhile bring 300 ml of water and sugar to the boil and let it stand for 10 minutes. Remove the syrup from the stove, add rose water and milk dough balls and leave to stand for about 30 minutes. Serve hot or cold.
