Sift the flour, cut the butter into cubes. Add some ice water and knead the dough. Place in the freezer for half an hour.
Roll out the chilled dough into a layer and place it in the mold so that the edges hang down by about 5 cm. Make several punctures in the dough with a fork and place the mold in the oven for 15 minutes. After baking, you can carefully trim the sides.
For the filling, cut the pumpkin into cubes and boil until soft, then puree in a blender with 100–150 ml of water.
Mix pumpkin puree, 4 eggs, 350 ml condensed milk and spices in a bowl.
Pour the filling into the mold, bake the pie for another 1.5 hours at 180 degrees.
You can serve the pie with a scoop of vanilla ice cream and coffee.
