2 tbsp all-purpose flour (to thicken)

🍳 Instructions
Make the crust
In a large bowl, mix flour and salt.
Cut in cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs.
Gradually add ice water, 1 tbsp at a time, until the dough comes together.
Divide into two uneven portions: one ⅔, one ⅓.
Flatten into discs, wrap in plastic, and chill for 30 minutes.
Prep the filling
In a large bowl, toss apple slices with sugars, flour, cinnamon, nutmeg, and lemon juice. Set aside.
Preheat oven & prep pan
Preheat oven to 375°F (190°C).
Line a 10×15-inch rimmed baking sheet with parchment paper.
Roll out the crust
On a floured surface, roll the larger dough disc into a 12×17-inch rectangle.
Carefully transfer to the baking sheet, pressing gently into the corners.
Trim edges if needed.
Add the filling
Spread apple mixture evenly over the crust, leaving a 1-inch border.
Top it off
Roll the smaller dough disc into a 10×13-inch rectangle.
Place over the apples.
Crimp edges with a fork or fold and press to seal.
Cut 4–5 slits in the top for steam to escape.
Glaze & bake
Brush the top with beaten egg.
Sprinkle with coarse sugar.
Bake for 40–45 minutes, until golden brown and filling is bubbling.
Cool 15–20 minutes before slicing.
Serve
Cut into squares or rectangles.
Serve warm — à la mode is highly encouraged!
🍹 For extra flavor, add a splash of vanilla or a pinch of cardamom to the filling.
