In a large skillet, combine the ground pork, lean ground beef, water, and finely diced onion.
Cover the skillet with a lid.
Cook over medium heat until the meat is fully cooked and the onion is tender.
Stir occasionally while cooking to break up the meat evenly.
In a separate pot, add the diced potatoes to lightly salted water.
Boil the potatoes until tender.
Drain the potatoes well.
Add the cooked potatoes to the meat mixture.
Add the black pepper, salt, cinnamon, allspice, and ground cloves.
Stir until the spices are evenly distributed throughout the meat and potato mixture.
Using a potato masher, lightly mash the mixture until the potatoes are partially broken down and the filling holds together.
Lightly flour a clean work surface.
Roll the pastry dough into two 11-inch circles.
Place one pie crust into the bottom of a pie plate.
Spoon the meat and potato filling evenly into the bottom crust.
Place the second pie crust over the filling.
Seal the edges of the top and bottom crusts together.
Flute the edges or press them with a fork.
Cut several small slits in the top crust to allow steam to escape.
Bake at 450°F for approximately 20 minutes, or until the crust is light golden brown.
Remove the pie from the oven.
Allow it to rest for a few minutes before slicing.
Serve warm.
