Whether it's the first batch of cookies your child has ever made or the hundredth you've baked yourself, you want them to be perfect. Even an excellent recipe can suffer from cooking on inferior bakeware. Made to withstand the rigors of commercial use, while still producing a professional product, this is a cookie sheet with staying power.
The large size of this cookie sheet lets you bake more in less time, which is great if you're baking dozens of cookies for a party, holiday celebration, or after-school snack. With this efficiency also comes quality: once available only to commercial kitchens, the sheet is made of professional-weight aluminized steel, so it won't buckle under intense heat and will consistently provide fast and even heat distribution. No need to turn the sheet midway through baking. Bakers unaccustomed to heavy-gauge aluminized steel should pay close attention at first since foods bake (and burn) more quickly. The pan will gradually darken with use, which will speed up baking time and require slightly lower oven temperatures.
The traditional uncoated surface of this sheet makes it extra rugged and a great conductor of heat, but this does mean butter, oil, or parchment paper should be used to prevent sticking. Greasing or lining the pan also simplifies cleanup since the pan can go from oven to dishwasher with no scrubbing in between. --Emily Wolf
