Ingredients:
- 320g all-purpose flour
- 225g unsalted butter, chilled and cubed
- 15g granulated sugar
- 5g fine sea salt
- 90ml ice water
- 1.5kg apples (Granny Smith and Honeycrisp), peeled, cored, and sliced
- 150g brown sugar, packed
- 8g ground cinnamon
- 0.5 tsp ground nutmeg
- 0.5 tsp ground allspice
- 15ml lemon juice
- 25g cornstarch
- 30g unsalted butter (for filling reduction)
- 1 large egg
- 2 tbsp demerara sugar
Instructions:
- Prepare the pastry by cutting 225g of chilled butter into the flour, sugar, and salt until pea-sized lumps remain. Gradually add ice water until the dough holds together. Divide into two disks, wrap, and chill for at least 1 hour.
- Toss sliced apples with brown sugar, cinnamon, nutmeg, allspice, and lemon juice. Let the mixture sit for 30 minutes to macerate and release juices.
- Drain the accumulated juices from the apples into a small saucepan. Add 30g of butter and boil for 3-5 minutes until the liquid reduces into a thick syrup.
- Roll out the bottom crust and fit it into a 9-inch glass pie dish. Toss the macerated apples with cornstarch and arrange them in the dish. Pour the reduced syrup over the fruit.
- Roll out the top crust and place it over the filling. Seal and crimp the edges, then cut vents in the top.
- Brush the crust with a beaten egg mixed with a teaspoon of water. Sprinkle generously with demerara sugar.
- Bake at 425°F (220°C) for the first 15 minutes to set the crust structure. Reduce oven temperature to 375°F (190°C) and bake for an additional 40 minutes until the crust is deep mahogany and the filling is bubbling.
