Cipaille Or Cipate (Layered Meat Pie)

Cut chicken, beef and pork into 1 inch cubes and place in a large bowl. Combine with onions; cover and refrigerate for at least 12 hours or overnight. Arrange salt pork evenly in the bottom of a 3 quart casserole, preferably cast iron with a cover. Layer with 1/3 of the meat mixture and 1/3 of the potatoes; season with 1/3 of salt, pepper and spices. Roll out half of the pastry slightly thicker than for a normal pie and arrange on the potato layer, cutting a small hole in the center. Repeat with 2 more layers of meat and potatoes seasoned with salt, pepper and spices. Cover with remaining pastry, cutting a small hole in the center. Slowly add enough chicken stock through the hole until liquid appears. Cover dish and bake in a preheated 400 deg F oven for 45 minutes or until liquid simmers. Reduce temperature to 250 deg F and continue to bake, covered, for 5 to 6 hours more or until top crust is a rich golden brown.
