Preheat your oven to 425°F (220°C).
In a bowl, mix flour, sugar, and salt.
Cut in butter until the mixture resembles coarse crumbs.
Stir in ice water, one tablespoon at a time, until dough forms.
Divide dough in half, shape into discs, and refrigerate for 30 minutes.
Roll out one disc on a floured surface to fit your pie pan.
Place the rolled dough in the pie pan, pressing it into the sides.
In another bowl, combine fruit, lemon juice, brown sugar, cornstarch, and cinnamon.
Pour the fruit mixture into the crust, spreading it evenly.
Roll out the second disc and place it over the filling, cutting slits for steam to escape.
Bake for 45-50 minutes until the crust is golden brown.
Let it cool before serving.
