Ingredients:
- 2.5 cups all-purpose flour (315g)
- 1 cup unsalted butter, chilled and cubed (226g)
- 1 tsp fine sea salt
- 7 tbsp ice water
- 1.2 kg Granny Smith and Honeycrisp apples, peeled and sliced 1/4 inch thick
- 0.75 cup granulated sugar (150g)
- 0.25 cup light brown sugar, packed (50g)
- 2 tbsp cornstarch
- 1.5 tsp ground cinnamon
- 0.25 tsp ground nutmeg
- 1 tbsp lemon juice
- 2 tbsp unsalted butter, for dotting
- 1 large egg
- 1 tbsp water
- 1 tbsp coarse sparkling sugar
Instructions:
- In a large bowl or food processor, pulse the flour, salt, and chilled cubed butter until the mixture resembles coarse crumbs with pea-sized chunks of butter remaining.
- Gradually add ice water one tablespoon at a time until the dough just holds together. Divide into two equal disks, wrap in plastic, and chill for at least 1 hour.
- In a large mixing bowl, toss the sliced apples with granulated sugar, brown sugar, lemon juice, cornstarch, cinnamon, and nutmeg. Let the mixture macerate for 30 minutes to draw out excess moisture.
- Preheat your oven to 425°F (218°C) and place a baking sheet on the middle rack to catch drips.
- Roll out one disk of dough on a floured surface and fit it into a 9-inch deep-dish pie plate. Fill with the apple mixture, packing them tightly, and dot the top with 2 tablespoons of butter.
- Roll out the second disk of dough and place over the apples. Trim, fold, and crimp the edges to seal. Cut vents in the top crust.
- Whisk the egg with 1 tablespoon of water to create an egg wash. Brush over the top crust and sprinkle with coarse sparkling sugar.
- Bake at 425°F for 20 minutes, then reduce heat to 375°F (190°C) and bake for another 35-40 minutes until the crust is mahogany brown and the filling is bubbling through the vents.
- Cool for at least 3 hours on a wire rack to allow the filling to set before slicing.
