Knead flour, 50 g fat, egg yolk and sweetness until smooth. Cover and chill for about 30 minutes. Grease 6 tartlet cups with removable base (approx. 10 cm Ø)
Divide the dough into 6 portions. Roll out each portion in between foil round (approx. 12 cm Ø). Line the moulds with the foil, press lightly and prick them more often. Pre-bake in the preheated oven (electric range: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 10 minutes.
Cut pears into very thin slices and mix with lemon juice. Place on the tartlet bottoms and bake for another 10-12 minutes
Warm the jam and spread on the pears. Let it cool down and remove from the moulds. Decorate with cranberries
