Granitestone’s Crisper Tray coated three times with our most durable non-stick Granitestone finish so nothing sticks. But the non-stick rack is raised to keep all the food up and off the tray, which allows heated air to flow evenly all around the food, making it crispy on all sides. And because the tray is raised all the grease and oil drips right through - so no more soggy foods, just delicious and crispy tasting. Granitestone’s Crisper Tray is oven rated up to 500 degrees, is dishwater safe and PFOA Free.
