In a large bowl, mix flour, sugar, and salt. Cut in the cold butter until the mixture resembles coarse crumbs.

Gradually add ice water, stirring until the dough comes together. Divide dough in half, wrap in plastic, and chill for 1 hour.

Preheat oven to 190°C.

Roll out one dough half on a floured surface to fit a 9-inch pie dish. Transfer to dish, pressing into the bottom and up the sides.

In a large bowl, combine sliced apples, cinnamon, sugar, lemon juice, and cornstarch. Toss to coat evenly.

Fill the pastry-lined pie dish with the apple mixture.

Roll out the remaining dough and cut into strips. Weave a lattice over the filling. Trim excess dough.

Bake for 50 to 60 minutes, or until the crust is golden brown and the filling is bubbly.

Serve warm with a scoop of vanilla ice cream.
