A pie plate is a shallow, round dish specifically designed for baking pies. Typically made from materials like glass, ceramic, or metal, pie plates come in various sizes, with a standard diameter of about 9 inches. They often have sloped sides and a fluted edge, which helps create a decorative crust. These plates are used to hold the pie crust and filling during baking. The design allows for even heat distribution, ensuring that the crust cooks properly. Many people use pie plates for both sweet and savory pies, making them a versatile kitchen tool for home bakers and professional chefs alike.
