Mix flour, icing sugar and salt in a bowl. Add the egg, butter in small pieces and about 1 tablespoon of cold water and knead everything into a smooth short pastry. Roll out the dough on a floured work surface to a circle (28-30 cm Ø) and line a greased tart tin with lift-off base (approx. 26 cm Ø) with it. Prick the bottom of the dough several times with a fork and sprinkle with breadcrumbs. Place the mould in a cool place for about 10 minutes. In the meantime, wash the apricots, drain well, cut in half and remove the stone. Drain the apricots well from the tin.
Put the apricots loosely into the tin. Bake in a preheated oven, lowest shelf 30-35 minutes. (Electric cooker: 200 °C/ circulating air: 175 °C/ gas: level 3). Mix apricot jam in a saucepan, add almonds and after 10-15 minutes spread evenly on the apricots with a spoon. Finish baking the tart. Remove from the oven and sprinkle with sugar crystals. Serve hot or cold. Serve with whipped vanilla cream
