Put the flour in a bowl. Make a depression in the middle. Warm the milk. Crumble the yeast, mix with 1 teaspoon of sugar and about 3 tablespoons of milk. Pour into the flour bowl, sprinkle with some flour from the edge.
Sprinkle the rest of the sugar and salt on the edge of the flour and place 75 g fat in flakes on top. Cover and leave to rise in a warm place for about 15 minutes until the yeast pre-dough has doubled. Add the remaining lukewarm milk and the egg.
Mix everything to a smooth dough with the dough hooks of the hand mixer. Cover and leave to rise for a further 30 minutes. Peel and quarter the apples and remove the core. Cut the apple quarters lengthwise.
Sprinkle with lemon juice so that the fruit does not turn brown. Roll out the dough on a greased baking tray with a lightly floured roll of dough. Place the apple quarters on the dough. Spread almond flakes and remaining fat in flakes on top.
Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) for 40-50 minutes. Heat the apricot jam in a small pot and coat the cake with it. Sprinkle with pistachios. Serve apple pie fresh.
