Ingredients

3 cups all-purpose flour
1 1/2 Tbsp. granulated sugar
1 1/2 tsp. salt
1 1/2 cups very cold butter, cubed
3/4 cup cold water
0.33 cup cornstarch
1/2 tsp. ground cinnamon
1/2 tsp. ground ginger
1/4 tsp. ground allspice
3 lb. Golden Delicious apples, peeled and chopped
1/2 cup brown sugar
4 tsp. lemon juice
2 Tbsp. heavy cream or milk
2 Tbsp. coarse sanding or turbinado sugar

Directions

1. Step 1In food processor, pulse flour, sugar, and 1 teaspoon salt until combined. Add half of butter; pulse until fine crumbs form. Add remaining butter; pulse just until coarse crumbs form. Add water in 2 batches, pulsing between additions and scraping side of bowl. Pulse just until dough starts to come together. Transfer dough to large bowl; gently knead 2 or 3 times until dough comes together. Divide into 4 equal-size mounds; shape into flat rectangles and wrap each tightly in plastic. Refrigerate at least 30 minutes or up to 2 days.
2. Step 2Preheat oven to 400 degrees F. Line 15- by 10-inch rimmed baking sheet with parchment paper. Spray lightly with nonstick cooking spray. In large bowl, whisk together cornstarch, cinnamon, ginger, allspice, and remaining 1/2 teaspoon salt. Add apples, brown sugar, and lemon juice, tossing until apples are well coated; set aside.
3. Step 3Place 1 piece dough on lightly floured work surface. Lightly flour dough and roll into 12- by 9-inch rectangle, lightly flouring and scraping as needed to prevent sticking. Transfer to prepared baking sheet, placing 9-inch side along longest side of pan. Repeat rolling with another piece of dough. Transfer to other side of prepared baking sheet, overlapping slightly with first piece of dough. Press seam together to seal. Spread apple mixture over dough in even layer.
4. Step 4Repeat rolling process with third piece of dough. Place rectangle on top of one side of apple mixture, arranging 9-inch side along longest side of pan. Repeat rolling process with remaining piece of dough. Place rectangle on top of other side of apple mixture, overlapping slightly with other piece of dough. Press seam together to seal. Pinch edges of dough together to enclose filling. Brush top with cream and sprinkle with sugar. Cut 4 slits in top crust. Bake 1 hour and 10 minutes or until top is deep golden brown. Cool on wire rack before serving. Pie can be made up to 1 day ahead and kept at room temperature, covered.
