Mix butter in pieces, flour, almonds, egg yolk, 50 g diabetic sweetener, salt and 2 tablespoons of cold water with the dough hooks of the hand mixer and quickly work into a dough with your hands. Wrap in cling film and chill for approx. 1 hour. Roll out the dough thinly on a floured work surface. Grease moulds and line with the dough. Prick the base with a fork and chill for 30 minutes. Bake in the preheated oven (electric cooker: 175°C/ convection oven: 150 °C/ gas: level 2) for 10-15 minutes. Allow to cool and remove from the tins.
In the meantime, thaw the raspberries and put them, except for 9 fruits, with 15 g diabetic sweetness into a high mixing bowl. Puree with the cutting stick and pass through a sieve. Stir in quark and put it into a piping bag with a small perforated spout. Inject the quark into the tartlets. Decorate with raspberries and, if desired, with lemon balm. Sprinkle with sprinkling sweetness if you like
