Because this tray conducts and retains heat, you’ll find it useful for cooking nachos, fajitas and other dishes on the grill, on the stovetop or in the oven – and then keeping them warm at the table. Or use it for serving chilled dishes: Just refrigerate or freeze the tray before use. Made from a patented aluminum alloy with a pewter-like appearance, it’s hand made at a family-owned Pennsylvania foundry established in 1892. Heatproof to 1000°F. Hand-wash. 16 1⁄2".
