Nordic Ware Adjustable Pie Crust Shield This handy baking tool is crafted from durable aluminium and slides easily over the rim of your pie or quiche, shielding the crust from direct heat while allowing the filling to finish cooking. Simply position the shield over the edge of your pie and it prevents the crust from over-browning while the filling finishes baking to perfection. It’s an essential tool for bakers who love serving beautifully browned, perfectly baked pies.
