This grill tray keeps an even temperature and holds its heat well after you've removed it from the grill, making it as useful for serving dishes as it is for cooking them. Conducts even heat for thorough cooking, then keeps food warm at the table. Also useful for serving chilled dishes - just refrigerate or freeze the tray before use. For use on a grill or stovetop, or in the oven. Heatproof to 1,000deg.F. Made from a patented aluminum alloy with a pewter-like appearance. Handmade by Wilton-Armetale.
