Grease a tart mould with a removable base (26 cm Ø). Mix 250 g flour, icing sugar and 1 pinch of salt. Add the egg, 125 g butter in pieces and about 1 tablespoon of cold water. Knead everything first with the dough hooks of the hand mixer and then briefly with your hands until smooth
Roll out the dough on a little flour until round (approx. 30 cm Ø). Line the mould with this and press the edges into the grooves. Prick the base several times with a fork and sprinkle with breadcrumbs. Chill for about 10 minutes.
Wash, halve and stone the apricots. Distribute in the mould. Bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 12 minutes
Warm the jam. First spread almonds, then jam on the apricots. Continue baking at the same temperature for about 20 minutes. Sprinkle with sugar crystals. Let cool down if necessary. Serve warm or cold
