Knead flour, 32 g diabetic sweetener, cold fat in pieces and 4-5 tablespoons of ice-cold water to a smooth dough. Cover and chill for about 30 minutes.
Wash the apples and cut them into slices. Sprinkle with lemon juice. Divide the dough into 6 equally sized pieces and roll out on a little flour in the size of the tartlet cups (approx. 8 cm Ø). Put the dough into the greased baking tins. Press the edge of the dough to a height of approx. 1 cm. Pre-bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 8 minutes
Cover the tartlets with apple slices and spread a thin layer of jam. Bake at the same temperature for another 20 minutes.
Let the cakelets cool down. Turn them over and let them cool down. Dust with 6 g diabetic sweetener. Cream yoghurt tastes good with it
For storage: freeze the tartlets and bake them in the oven (approx. 150 °C) for about 10 minutes if necessary
