This is the version I use for most of my sweet tarts. It's delicious.
Roll out and bake the pastry: Preheat your oven to 180°C (350°F). Remove the pastry from the refrigerator and roll it out on a lightly floured work surface (using gluten-free flour). I personally roll it out between two sheets of cling film. Then place it in a tart tin or cut out circles for tartlets. Prick the base of the pastry with a fork to prevent it from puffing up during baking. (This is optional if you are baking the tart directly with the filling).
