Two surfaces make the difference. The revolutionary Slide Nonstick surface releases foods effortlessly, essential for creating tender omelettes and delicate sauces, while the specially textured Sear Nonstick surface seals in flavor to create juicy braised beef, tuna and vegetables. Each surface is designed to enhance the specific cooking purpose of the pan. So your mushroom and gruyere omelets are moist and flavorful and your salmon filets are seared to perfection. The perfect pair −in one set.
