Successful baking relies as much on good tools as it does on techniques and ingredients. Our signature professional-quality pans offer superb performance and the impeccable release of our Goldtouch nonstick coating. This special set includes all the essentials for everyday baking tasks. Commercial-grade aluminized steel distributes heat quickly and evenly for consistent baking results. Goldtouch ceramic coating reinforces our pans making them more resistant to abrasion than normal non-stick surfaces and releases food with ease. Coated wire reinforcement along the rim of the half-sheet pan maximizes durability and resistance to rust and warping. Unique diamond-textured surface strengthens sheet pans while increasing airflow for even baking. Extended edge on muffin pan provides a secure grip, making it easy to transfer the pan to and from the oven. Extra-thick rolled edge of round cake pans ensures maximum durability and warp resistance.
