Grease 4 tartlet cups with a removable base (each 12.5 Ø; approx. 3 cm high). Wash and clean the strawberries and, depending on size, cut them in half or into pieces.
Mix flour, sugar, vanillin sugar and 1 pinch of salt in a bowl. Add butter, egg and possibly about 1 tablespoon of cold water. Knead everything first with the dough hooks of the hand mixer, then briefly with your hands to form crumbles.
Spread a good half of the crumbled dough into the moulds and press down as the base and rim. Spread about 1 tbsp. breadcrumbs on each base and spread the strawberries on top. Sprinkle the rest of the crumbles on top, rubbing them between your fingers.
Bake in the preheated oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3) for 40-45 minutes. Leave to cool in the tins. Remove the tartlets from the ramekins, dust with icing sugar and serve lukewarm or cold.
Vanilla ice cream tastes good with it.
