In a large skillet, combine the ground pork, ground beef, onion, and water. Cover and cook over medium heat until the meat is fully cooked and the onions are tender, stirring occasionally.
Cook the potatoes
In a separate pot, bring lightly salted water to a boil. Add the diced potatoes and cook until tender. Drain thoroughly, then add the potatoes to the meat mixture.
Season and mash
Stir in the cinnamon, cloves, all-spice, salt, and pepper. Using a potato masher, mash the mixture until well combined. A slightly rustic texture is ideal.
Prepare the pie crust
On a lightly floured surface, roll out the pastry dough into two 11-inch circles. Line the bottom of a pie plate with one circle of dough.
Assemble the pie
Spoon the meat and potato filling into the prepared pie crust. Cover with the second circle of dough, ensuring the edges are sealed.
Bake
Flute the edges of the crust and cut several slits in the top to allow steam to escape. Bake in a preheated oven at 450°F (232°C) for 20 minutes, or until the crust is golden brown. Remove from the oven and allow to cool slightly before serving.
