Mix flour, 75 g sugar and 1 pinch of salt. Add butter in pieces and 4-5 tablespoons of ice-cold water. Knead everything first with the dough hooks of the hand mixer, then quickly with your hands to a smooth short pastry.
Wrap in foil and chill for about 30 minutes.
For the filling, peel, quarter, core and cut apples into small cubes. Mix first with lemon juice, then with 3 tablespoons of sugar, starch and cinnamon.
Grease a pie or tart mould with a removable base (26 cm Ø). Roll out 2/3 of the dough on a little flour to a circle (32-34 cm Ø), chill the rest of the dough again. Place the dough sheet in the form and press it up at the edge of the form.
Cut off excess dough, knead and chill separately. Spread apples on the dough base.
For the lid, roll out a third of the dough round on a little flour (approx. 26 cm Ø) and place over the apples. Press the edges of the dough well together.
Preheat oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3). Roll out the dough and cut out flowers, leaves or similar. Whisk egg yolk and 2 tbsp. water. Spread the dough lid with it and decorate with the dough motifs.
Bake in a hot oven for about 1 hour until golden brown. Let it cool down. Serve lukewarm or cold with whipped cream.
