Knead the flour, 60 g butter, salt and 1 tablespoon of water first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Wrap the dough in foil and chill for about 30 minutes
Wash, peel and quarter apples, remove core. Cut each quarter into about 5 slices. Grease a tart mould (bottom 22 cm Ø; top 26 cm Ø; height approx. 4 cm) with lift-off base. Roll out the dough on a floured work surface until round (approx. 28 cm Ø). Line the mould with the dough and press on. Place the apple slices tightly in a circle, the apples may overlap slightly
Spread 25 g butter in flakes on the apple slices and sprinkle with sugar. Bake in the preheated oven (electric oven: 175 °C/ convection oven: 150 °C/ gas: level 2) for 50-60 minutes on the 2nd rack from the bottom, possibly 5 minutes before the end of the cooking time on the top rack. Remove the tart and let it cool down on a cake rack. Bring the jelly and 1 tbsp. water to the boil briefly and coat the tart with it. Remove the tarte from the tin and serve with whipped cream or vanilla ice cream
waiting time approx. 1 1/2 hours
