Step 1

Make the crust: Whisk the flour, granulated sugar and salt in a large bowl. Rub the butter pieces into the flour using your fingers until pea-size pieces form. Drizzle in the vinegar and ice water; stir gently with a fork to combine. If the dough doesn’t hold together when you squeeze it, add more ice water, 1 tablespoon at a time. Turn out the dough onto a piece of plastic wrap and form into a disk; wrap tightly. Refrigerate until firm, at least 1 hour or overnight.

Step 2

Roll out the dough on a lightly floured surface into a 13-inch round. Ease into a 9-inch pie plate. Trim the edges, leaving a 1-inch overhang, then tuck the overhanging dough under itself; crimp the edges with a fork. Refrigerate until firm, at least 1 hour or overnight.

Step 3

Meanwhile, make the crumb topping: Mix the flour, brown sugar, cinnamon and salt in a medium bowl. Rub the butter into the mixture with your fingers until no longer floury and crumbs form. Freeze until ready to use.

Step 4

Make the filling: Place a foil-lined baking sheet on the lowest oven rack; preheat to 400˚. Mix the apples, melted butter, both sugars, flour, lemon juice, cinnamon and salt in a large bowl. Spoon the filling into the chilled pie crust. Pat the crumb mixture on top.

Step 5

Bake the pie on the hot baking sheet until lightly browned, about 30 minutes. Reduce the oven temperature to 350˚ and bake until the apples are completely soft when pierced with a paring knife, 60 to 80 more minutes. (If the topping is getting too dark, cover loosely with foil.) Transfer the pie to a rack to cool completely.
