Separate 1 egg. Knead flour, cold fat in pieces, 1 egg yolk, 12 g diabetic sweetener and salt with the dough hooks of the hand mixer. Then knead to a smooth dough with your hands. Cool for about 30 minutes
Lightly grease 8 brioche or tartlet cups (approx. 7 cm Ø) and dust with a little flour. Roll out dough thinly on a little flour. Cut out 8 circles (each approx. 9 cm Ø) and place them in the moulds. Spread the compote evenly on top
Separate the other egg. Stir the quark, egg yolk, lemon rind and 12 g diabetic sweetener until smooth. Beat 2 egg whites until stiff, fold in. Spread the mixture over the compote
Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 35-40 minutes. Turn out the tartlets and let them cool down. Sprinkle with 3 g diabetic sweetness
