Mix 100 g butter in pieces, 50 g sugar, flour, egg and salt to a short pastry. Cover and chill for about 30 minutes. In the meantime peel apples, cut out the core and cut apples crosswise in half. Caramelise 50 g sugar and almonds in an ovenproof pan (22 cm Ø) until light brown. Add 20 g butter and take the pan off the heat. Place the apple halves in the pan with the cut surface facing upwards.
Braise at medium heat for about 10 minutes. Let cool down for 15 minutes. Roll out the dough on a floured work surface to a circle (22 cm Ø). Place on the apples and prick with a fork. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 35 minutes. Immediately turn out of the tin onto a plate and let it cool down
Preparation time approx. 1 hour 15 minutes
