Cover with the remaining pastry dough. Make a hole in the centre of the pie. Place an aluminum foil funnel, 2.5-cm (1-inch) deep, to prevent the juices from overflowing. Decorate the pie with the leftover dough. Bake for 1 hour, reduce the oven’s temperature to 120 °C (250 °F). Bake for another 4 hours. If the pie gets too dark, cover with aluminum foil.
