Start by mixing your gluten free all-purpose flour, salt, and sugar. Then add and cream the dry ingredients with cold butter by hand or with the stand mixer.
Add the water gradually while mixing until the dough holds together.
Move the dough to a cold surface lightly dusted with flour. Give it a quick knead to shape it into a ball.
Form the dough into a rounded square. Wrap in cling film and let the dough rest in the fridge for 30-45 minutes.
Roll out the cold dough to a thickness of approximately 3-4 mm (0.16 in) between sheets of parchment paper to prevent sticking.
You can use a Measuring Dough Strip when rolling out dough. This will ensure a uniform thickness and expedite the process.
Place the dough into a 9-inch (23 cm) pie dish. Press on the sides, trim the edges, and poke a few holes in the bottom using a fork. Refrigerate while mixing the pie filling.
