Ingredients

• 2½ cups all-purpose flour
• 1 teaspoon salt
• 1 tablespoon sugar
• 1 cup (2 sticks) cold unsalted butter, cubed
• 6–8 tablespoons ice water
• 3 lbs mixed apples (Granny Smith and Honeycrisp), peeled and sliced
• ¾ cup sugar
• 3 tablespoons cornstarch
• 1 teaspoon cinnamon
• ¼ teaspoon nutmeg
• ¼ teaspoon allspice
• 1 tablespoon apple cider vinegar
• 1 tablespoon butter, cut into small pieces
• 1 egg, beaten with 1 tablespoon water

Method

1. Make the crust: combine flour, salt, and sugar. Cut in cold butter until mixture resembles coarse crumbs with some pea-sized pieces.
2. Add ice water one tablespoon at a time, mixing gently, until dough just comes together. Divide in half, flatten into discs, wrap and refrigerate 1 hour.
3. Toss apples with sugar, cornstarch, spices, and vinegar. Let sit 15 minutes.
4. Preheat oven to 425°F. Roll out one disc to fit a 9-inch pie dish. Line the dish.
5. Pour in apple filling, mounding in the center. Dot with butter pieces.
6. Roll out second disc. Lay over filling, crimp edges to seal, cut vents. Brush with egg wash.
7. Bake 20 minutes at 425°F, then reduce to 375°F and bake 40 more minutes until golden and bubbling.
8. Cool at least 2 hours before cutting — the filling needs time to set.
