Cut butter roughly into cubes. Knead well with flour, almonds, 20 g diabetic sweetener, salt and about 4 tablespoons of water. Wrap short pastry in foil and put it in a cool place for about 30 minutes
Roll out the short pastry between 2 layers of cling film in round form (approx. 30 cm Ø). Place the dough in a greased tart tin (26 cm Ø), pressing the edge lightly. Chill the tart mould briefly. Stir sour cream, vanilla flavour, 60 g diabetic sweetener and eggs until smooth. Pour the sour cream mixture onto the shortcrust pastry. Spread blackberries over it. Bake the tart in the preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) for 45-50 minutes on the bottom shelf of the oven. Take out, let cool down
Waiting time approx. 30 minutes / 1 1/2 BE
