2 pre-made or homemade pie crusts (top and bottom)
6 cups Granny Smith or Honeycrisp apples, peeled, cored, and sliced
1 ½ cups fresh or frozen cranberries
¾ cup granulated sugar
¼ cup light brown sugar, packed
2 tablespoons cornstarch
1 teaspoon ground cinnamon
¼ teaspoon ground nutmeg
1 tablespoon lemon juice
1 tablespoon unsalted butter, cut into small pieces
1 large egg (for egg wash)
1 tablespoon coarse sugar (optional, for topping)
Instructions
Preheat your oven to 400°F (200°C). Roll out one pie crust and fit it into a 9-inch pie plate. Trim the edges, leaving a slight overhang, and place it in the refrigerator while you prepare the filling.
In a large mixing bowl, combine the sliced apples, cranberries, lemon juice, granulated sugar, brown sugar, cornstarch, cinnamon, and nutmeg. Toss gently until all the fruit is evenly coated with the sugar and spices.
Pour the fruit mixture into the chilled bottom crust, mounding it slightly in the center. Take the small pieces of butter and dot them evenly over the top of the fruit filling.
Place the second pie crust over the filling. You can do a solid top with vents cut into it, or cut the dough into strips to create a lattice pattern. Seal the edges by crimping them with your fingers or a fork.
Whisk the egg with a tablespoon of water and brush it lightly over the top crust. Sprinkle with coarse sugar if desired. Bake for 20 minutes, then reduce the heat to 375°F (190°C) and bake for another 30 to 35 minutes until the crust is golden brown and the filling is bubbling.
Remove the pie from the oven and place it on a wire rack. It is crucial to let the pie cool for at least 2 to 3 hours before slicing. This allows the juices to thicken so the slices hold their shape.
