As a serious cook, I look for tough uncoated surfaces that won't rust or require such ginger care. The pan is sturdy, priced right, fits perfectly in the oven without a rack and cleans up like a dream. NordicWare is great!
Whether roasting vegetables, roasting a turkey or baking sheets of brownies or cookies, it distributes heat evenly without burning and does a consistent job every time. No need for wooden or teflon utensils, you can use whatever you want, whenever you want. If you're looking for a non-stick surface, add parchment or a silpat that browns cookies evenly and lets you slide them right off.
I like this pan so much, I own 4 so I can rotate them and do a great amount of baking without waiting for the sheets to cool. It also ensures they stack nicely in the cabinet. The lid is a nice addition, making it convenient and secure to store cookies and brownies right on the sheet without removing them or worrying if the saran wrap or foil will slip off.
