Mix butter, icing sugar, flour, egg yolk and salt with the dough hooks of the hand mixer to a smooth dough. Shape into a ball with your hands, cover and chill for approx. 30 minutes. In the meantime, blanch peaches with hot water, rinse with cold water, peel, halve and sprinkle with lemon juice. Roll out the dough on a floured work surface to a thickness of about 5 mm. Cut out a circle (28 cm Ø) and place it in a sewing or pie dish (26 cm Ø). Press the rim up a little.
Prick the dough several times with a fork. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 25 minutes. Let it cool down. Melt the chocolate coating over a hot water bath. Carefully turn out the cooled baking tin. Place the shortcrust pastry base on a cake plate and spread the inside with chocolate coating. Mix quark, mascarpone, lemon peel, vanillin sugar and 75 g sugar. Select the raspberries and blackberries. Pour cream into the cake shell. Dab the peaches dry. Spread on the cream with the cut surface facing upwards.
