Preheat oven to 200 ° C convection.
Mix flour, sugar and salt in a large bowl and add butter in pieces. Then knead with water and egg yolk to a homogeneous dough and let rest for at least half an hour in the refrigerator. Then roll out the dough, place in a tart tin and prick small holes in the ground with a fork. Bake the soil for about 15-20 min.
For the filling, stir the eggs, egg yolk, pear-apple spread and cream until smooth with a whisk. Put the stuffing on the ground and bake for about 20-25 min. Allow the tart to cool on a wire rack.
