This is an easy-to-make pie for the Thanksgiving holidays.
Preheat oven to 350 degrees. In a large mixing bowl, combine sugar, flour, cinnamon, nutmeg, and salt. Peel and core apples; slice 1/2 inch thick, and add to bowl. Drizzle lemon juice on top; gently toss to coat.
On a lightly floured work surface, roll out dough to a 20-inch round, about 1/8 inch thick. Wrap dough around rolling pin; carefully unroll over a 9-inch pie plate, leaving overhang. To fit into pan, lift edge of dough, and let dough drape inward. Use kitchen scissors to trim to a 3-inch overhang.
Mound apple mixture into pie dough. Gently fold dough over apples. Lightly brush dough with cold water, and sprinkle with remaining tablespoon sugar.
Bake on a rimmed baking sheet, rotating once, until crust is golden and filling is set (it will be juicy but not runny), about 1 1/2 hours (tent with foil if crust browns too quickly). Cool completely before serving.
This pie is best baked a day ahead to allow the filling to set completely; once it has cooled, cover with foil, and keep at room temperature. To serve warm, reheat in a 200-degree oven just before serving.
