Once the dough has chilled overnight and has the texture and consistency of saltwater taffy, it's ready to be rolled. Liberally sprinkle a work surface with flour (see baker's notes). Unwrap the circular portion of dough (but keep the rectangular portion in the fridge!) and place it on the work surface, sprinkling its top with flour. If the dough is hard, let it rest for a few minutes. If the dough seems too sticky at first, add flour liberally. Use a rolling pin to roll with light pressure, from the center out, moving the pie dough around every quarter to roll it evenly. Roll the the dough to about 11 to 12 inches in diameter and about 1/4 inch thick (place your pie plate upside down over it to check its size).
