Method
Make the Dough: In a food processor, combine flour, salt, and sugar. Add cubed butter and pulse until crumbly. Add eggs and milk, pulsing until dough forms. Divide into two balls, wrap in plastic wrap, and refrigerate for at least 1 hour.
Prepare the Filling: In a large bowl, mix ricotta, eggs, nutmeg, and black pepper. Stir in the cubed meats and cheeses until everything is well combined.
Assemble the Pie: Preheat the oven to 375°F (190°C). Roll out the larger dough ball to fit the bottom of your pie dish. Add the filling and top with the remaining dough, sealing the edges. Brush the top with a beaten egg yolk mixed with water.
Bake: Place in the oven on the lowest rack and bake for 1 hour, until golden brown. Let it cool before slicing.
Tips & Variations
Meat Variations: You can substitute other cured meats like pancetta or bresaola if you prefer.
Dairy-Free Substitution: Use dairy-free cheese and butter for a dairy-free version of this pie.
Freezing: Pizza Chiena can be frozen before baking. Wrap it tightly in plastic and foil, and bake from frozen, adding a few extra minutes to the cooking time.
