For the filling:
Cook the pumpkin in the oven (we recommend the Delica variety) until cooked and peel it.
Blend the pulp together with the sugar, milk and cornstarch by sieving it.
Finally, add the mix of spices, adjusting them to taste, consisting of:
cinnamon, nutmeg, cloves, ginger.
For the pastry:
Quickly
mix cold butter and flour together, obtaining a flour, add salt and sugar and cold water. It works everything quickly, without heating it up.
You will get a fairly homogeneous dough, let it rest 10 minutes in the fridge, then roll it out on the floured surface, forming a sheet about half a centimeter thick.
Move the pastry to a glass or ceramic pie pan, remove the excess from the edges, prick the bottom with the tines of a fork and pour over the filling.
Level the mixture, decorate the edges of the tray by pressing a little with your fingers and bake in a hot oven at 175°C for 1 hour. Bake and let it cool for at least a couple of hours, before serving.
