Cut butter into large cubes. Knead with flour, 50 g diabetic sweetener, salt, 1 egg and 1-2 tablespoons cold water. Grease a tart tin (26 cm Ø) with a removable base. Roll out the dough between 2 layers of cling film round (approx. 30 cm Ø). Line the mould with it, press the dough on the edge. Prick the base several times with a fork, cover and chill for approx. 30 minutes. Pre-bake the peach tart in a preheated oven (electric cooker: 175 °C / fan oven: 150 °C / gas mark 2) for approx. 15 minutes.
Drain peaches well. Mix yoghurt, 60 g diabetic sweetener, grated lemon rind, 2 eggs and pudding powder. Cover the tarte base with peaches and spread the glaze over them. Place the mould on the grid of the oven. Continue baking at the same temperature for 30-35 minutes. Pass the jam through a sieve and brush the peaches with it. Let it cool down
