How can I keep a pie crust from shrinking when I prebake it?

A pie crust that shrinks a great deal is also one that is tough. This is a result of too much water, too high a protein flour, and or overhandling of the pastry. My cream cheese pie crust in The Pie and Pastry Bible is one that shrinks very little.But it will help any recipe to allow the dough to relax after rolling and lining the pan for at least 1 hour, covered and refrigerated. Lining the crust with parchment and dried beans or peas until it has set also helps to keep itís shape. A coffee filter, the sort used for coffee urns, is just the right size and shape to line the pastry.
