Too many home kitchens have a hodgepodge of clunker baking sheets. You know the ones: Warped. Wobbly. Dented. So thin they’re apt to char the undersides of cookies before browning the tops.If you cook or bake at all, you should own a solid baking sheet. Really, you should own several. A quality rimmed baking sheet is inexpensive and incredibly useful. Beyond cookies, it’s great for roasting vegetables, making pizzas, toasting nuts, catching drips from a pie as it bakes, or cooking a quick sheet-pan dinner.After hours of baking and tasting cookies — someone had to do it — among other tests, we’ve concluded that the Nordic Ware Naturals Baker’s Half Sheet is the best all-purpose baking sheet.
