Preparation

• Make the pie crust recipe and chill per instructions while preparing the filling. Preheat oven to 425˚F.
• Melt butter in a medium saucepan over medium heat. Whisk in 3 tablespoon flour then simmer for 1 minute, whisking constantly. Whisk in ¼ cup water and 1 cup sugar and bring to a boil. Reduce heat and continue simmering for 3 minutes, whisking frequently then remove from heat.
• Peel, core, and thinly slice 7 cups of apples and place them in a large bowl. Sprinkle the top with 1 ½ teaspoon cinnamon and toss to combine. Pour the sauce over the apples and stir to coat the apple slices.
• Sprinkle your work surface with flour and roll out the bottom pie crust to a 12" diameter circle. Wrap it around your rolling pin to transfer it to the 9" pie plate. Add apple mixture, mounding slightly in the center and being careful not to get the filling on the edges which would make it difficult to seal.
• Roll the second crust into an 11" round and cut into 10 even-thickness strips using a pizza cutter. Arrange strips in a woven lattice pattern over the top. Beat together 1 egg and 1 tablespoon water and brush the top with egg mixture.
• Bake at 425˚F in the center of the oven for 15 minutes. Reduce the heat to 350˚F and continue baking for another 45 minutes or until the apples are soft and the filling is bubbling through the vents for at least 5 minutes. Rest at room temperature for 1 hour before serving.
