Warm up the milk. Dissolve yeast in it. Put flour, 100 g sugar, salt and soft fat in flakes into a mixing bowl. Pour in the yeast milk and work into a smooth dough with the dough hook of the hand mixer. Cover and leave to rise for approx. 45 minutes in a warm place. In the meantime drain plums well. Collect the juice and fill up with peach juice to just under 1/2 litre liquid. Dice plums
Stir pudding powder into 4 tablespoons of juice until smooth. Bring 1 teaspoonful of cinnamon, remaining sugar and juice to the boil. Stir in the whisked pudding and bring to the boil. Fold in plums. Let the compote cool down
Knead the yeast dough again. Roll out to a rectangle of approx. 36X48 cm on a little flour. Cut out 12 squares (approx. 12 x 12 cm). Separate the egg. Mix the egg yolk in 1 tablespoon of water
Place plum compote in the middle of the dough squares. Coat the edges with egg white. Fold into a triangle. Press the edges of the dough well with your finger or a fork
Spread the yeast dough pockets with egg yolk. Place on a baking tray lined with baking paper and bake in the preheated oven (electric range: 200 °C/ convection oven: 175 °C/ gas: level 3) on the middle shelf for approx. 10 minutes. Dust with icing sugar and some cinnamon. Serve with vanilla cream
