For the dough, sift the flour, add the other ingredients, and knead a soft dough. Let it rest in the fridge for 20 minutes.
For the filling, melt the butter with sugar, vanilla, and cinnamon in a pot. Add the pears and simmer on low heat for about 15 minutes.
Finally, add the raisins soaked in rum. Dissolve the starch in 100 ml cold water, add it to the pears while stirring continuously, and remove from heat.
Roll out 2/3 of the dough to a thickness of 0.5 cm and spread it in a 22 cm pie pan. Prick the bottom with a fork and bake at 180 degrees for about 10 minutes until the edges are golden.
Sprinkle breadcrumbs on the baked base and distribute the filling. Roll out the remaining dough and cut strips to create a lattice on top.
Before baking, beat the yolk with milk or cream and brush it on the lattice. Bake the pie at 180 degrees until the lattice is golden, about 20 minutes.
