Ingredients List:

For the Crust:
3 ¾ cups all-purpose flour (470g)
1 ½ tablespoons sugar
1 ½ teaspoons salt
3 sticks unsalted butter (340g), cold & cubed
¾ cup very cold water
For the Filling:
3 ½–4 lbs apples, peeled and chopped (approx. 10 cups)
Juice of 1 lemon
⅔–¾ cup sugar (adjust to taste)
3 tbsp cornstarch
1 tsp cinnamon
¼ tsp nutmeg
¼ tsp allspice
⅛ tsp salt
To Finish:
2 tbsp heavy cream OR 1 egg beaten with 1 tbsp water

Step-by-Step Instructions:

Step 1: Prepare the Dough
Whisk flour, sugar, and salt in a bowl.
Cut in cold butter until pea-sized crumbs form.
Add water gradually, mixing gently until dough holds together.
Divide into 2 portions (one slightly larger), shape into rectangles, wrap, and chill at least 2 hours.
Step 2: Make the Filling
Toss chopped apples with lemon juice.
In another bowl, combine sugar, cornstarch, cinnamon, nutmeg, allspice, and salt.
Add spice mix to apples and toss to coat.
Step 3: Assemble the Pie
Preheat oven to 375°F (190°C); line a 10×15-inch sheet pan with parchment.
Roll larger dough to 18×13 inches; press into pan and chill.
Roll smaller dough to 16×11 inches.
Spread apple filling in crust, top with remaining dough.
Crimp edges and cut slits on top. Brush with cream or egg wash.
Place pan on larger tray to catch drips.
Step 4: Bake
Bake 40–45 minutes or until crust is golden and filling is bubbly.
Cool 45 minutes before slicing.

Tips for Success:

Use a mix of tart and sweet apples for depth.
Keep ingredients cold for flakier crust.
Sprinkle graham cracker crumbs on bottom crust to prevent sogginess.
Reheat slices in the oven for best texture.
