2. In a mixing bowl, combine flour and salt. Add the cold butter and mix until the mixture resembles coarse crumbs.
3. Gradually add ice water, mixing until the dough comes together. Divide the dough into two discs, wrap in plastic, and refrigerate for at least 30 minutes.
4. In another bowl, combine cherries, sugar, cornstarch, and vanilla extract. Set aside.
5. Roll out one disc of dough and fit it into a pie dish. Add the cherry filling.
6. Roll out the second disc of dough and place it over the filling. Trim and crimp the edges. Cut a few slits in the top crust to allow steam to escape.
7. Bake for 50 minutes or until the crust is golden and the filling is bubbly. Let cool before serving.
