Why is it important to flatten pie dough with a rolling pin?

Answer by  hickchick09 (36)

It is important to flatten pie dough with a rolling pin because you need the dough to be thin and crisp. It also allows the pie to get even cooking. You do not need to use a rolling pin you could also use a regular drinking glass to get the dough to the right consistency.

A rolling pin should always be used to flatten pie dough because flattening by hand will cause the crust to be tough.
