Ingredients:
- 350g All-Purpose (Plain) Flour
- 225g Unsalted Butter (very cold, cubed)
- 1 tablespoon Granulated Sugar
- 1 teaspoon Fine Sea Salt
- 100–120ml Ice Water
- 4 kg Cooking Apples (peeled, cored, and thickly sliced)
- 150g Light Brown Sugar (packed)
- 50g Granulated Sugar
- 3 tablespoons All-Purpose (Plain) Flour or Cornflour (Cornstarch)
- 1 ½ teaspoons Ground Cinnamon
- ½ teaspoon Ground Nutmeg
- 1 tablespoon Lemon Juice (freshly squeezed)
- 1 tablespoon Unsalted Butter (cubed, for dotting)
- 1 Large Egg (beaten)
- 1 tablespoon Milk or Cream
- 1–2 tablespoons Coarse Turbinado Sugar
Instructions:
- Phase I: Pastry Preparation. Combine flour, sugar, and salt in a large bowl or food processor. Add cold, cubed butter. Pulse or use fingertips until the mixture resembles coarse breadcrumbs with pea-sized butter pieces remaining.
- Slowly stream in ice water, mixing only until the dough just comes together. Divide the dough into two slightly unequal discs, wrap tightly, and refrigerate for at least 1 hour.
- Phase II: Filling Assembly. Peel, core, and thickly slice the apples. In a separate bowl, whisk together brown sugar, granulated sugar, flour/cornstarch, cinnamon, and nutmeg.
- Toss the sugar-spice mixture and lemon juice thoroughly with the apple slices until every piece is coated.
- Phase III: Assembly & Baking. Roll out the larger dough disc and carefully transfer it to a 9-inch pie plate. Trim edges, leaving a 1-inch overhang.
- Spoon the apple filling into the crust, mounding it slightly. Dot the top of the apples with the tablespoon of cubed butter.
- Roll out the second dough disc. Place it over the filling (or use strips for a lattice). Crimp the top and bottom edges together firmly to seal, trimming excess dough.
- Cut 4–5 steam vents in the top crust. Brush the top surface evenly with the egg wash (egg + milk) and sprinkle generously with coarse sugar.
- Place the assembled pie on a preheated baking sheet. Bake at 400°F (200°C) for 20 minutes. Reduce heat to 375°F (190°C) and bake for another 45–55 minutes until the crust is deep golden brown and filling is bubbling.
- Allow the pie to cool on a wire rack for a minimum of 3 hours before slicing to allow the filling to set properly.
