Method
Make the crust
- Whisk the flour and salt together in a large bowl.
- Work the cold butter into the flour mixture with a pastry cutter until pea-size pieces remain.
- Sprinkle in the ice water and toss with a fork until the dough begins to clump when pressed.
- Divide the dough into portions of about three-quarters and one-quarter, and shape each into a disk.
- Wrap the dough disks and refrigerate for 1 hour.
Cook the filling
- Stir the apples, granulated sugar, cornstarch, cinnamon, and lemon juice together in a medium saucepan.
- Cook over medium heat for 5 to 7 minutes, stirring often, until the apples begin to soften and the juices thicken.
- Transfer the filling to a bowl and cool completely.
Assemble and bake
- Heat the oven to 375°F and lightly grease the cups of a standard 12-cup muffin pan with the vegetable oil.
- Roll the larger dough portion between sheets of parchment to 1/8-inch thickness.
- Cut twelve 4 1/2-inch rounds, rerolling scraps as needed.
- Roll the smaller portion and cut twelve 2 3/4-inch rounds.
- Press one larger dough round into each muffin cup, then divide the cooled filling evenly among the cups.
- Place a smaller dough round over each pie and press it against the bottom crust to seal.
- Cut a small vent in each top.
- Brush the tops with the beaten egg and sprinkle with coarse sugar.
- Bake for 25 to 30 minutes, until the crusts are golden and filling bubbles through the vents.
- Cool the pies in the pan for 15 minutes, then loosen the edges and transfer them to a wire rack.
- Cool for at least 15 minutes before serving.
Notes
For the flakiest crust, keep the butter cold and work it in only until pea-size pieces remain. Store covered in the refrigerator for up to 3 days; freezer-friendly. For an egg-free finish, omit the egg wash and brush the tops lightly with milk instead.
