Remove the dough from the refrigerator and roll it out on a lightly floured work surface. Lightly flour the top as well if it starts to stick to the rolling pin.
Roll the dough to about 3 mm (1/8 inch) thick, giving it a quarter turn regularly to keep it even and round.
Form a disc larger than the diameter of the pan, keeping in mind the height of the sides and leaving extra dough if you want to create a thicker crimped edge.
Note: If the dough becomes too soft as you roll it, transfer it to a baking sheet lined with parchment paper and chill it in the refrigerator for about 15 minutes.
Fold the dough in half and place it in the center of the pan, then gently unfold it and ease it into the bottom and sides without stretching or tearing it.
Press the dough against the sides and bottom of the pan, making sure to remove any air bubbles or creases.
Trim the excess dough flush with the pan for a classic crust, or leave about 2 cm (3/4 inch) overhanging. Fold this excess back onto itself toward the inside of the pan to form a slightly thicker edge.
Decorate the edge with your fingers, a crimper, or a fork, depending on the style you want. For the hand crimping technique, place your index finger and thumb on the outside of the crust and press from the inside with the thumb of your other hand.
Prick the bottom and sides of the dough with a fork, then place the pan in the refrigerator or freezer for a few minutes to firm up the dough before baking.
Note: You can fill and bake the pie at this stage, but I recommend giving the crust at least a partial bake until it turns lightly golden. It really makes a difference in flavor.
