The de Buyer baking tray with slanted edges is a professional-grade tool designed for baking cakes and croissants. Crafted from 1.2 mm thick black sheet metal, this rectangular tray measures 53 x 32.5 x 1 cm and features a slightly roughened surface that creates air cushions between the food and the metal to ensure even heat distribution. Because of its high heat conduction, you can expect consistent results across the entire surface. To maintain the black finish and prevent rust, you should grease the tray both before and after each use. This particular model is not suitable for the dishwasher, so it requires manual cleaning to preserve its integrity over time.
