Question: what is the difference between shortcrust and pie crust?
Answer: Shortcrust pastry (called pâte brisée in French) does not puff up in the oven because it does not have any leavening agents. Shortcrust pastry falls apart easily when eaten. Shortcrust pastry is made with half the amount of fat as flour (mass wise). Shortcrust pastry is the same thing as pie dough.
