Set oven to 350°F (180°C) and place a rack in the center. Roll the chilled dough into a thin sheet (5mm) between parchment sheets. Line your tart pan, patching any broken spots. Prick the bottom with a fork, pour in the filling, level it out, and bake for 45 minutes or until golden brown. Cool completely on a rack for about an hour.
