How do baking sheet liners work?

Baking sheet liners are typically made from materials like parchment paper, silicone, or aluminum foil, designed to create a non-stick surface for baking. They prevent food from sticking to the baking sheet, making it easier to remove baked goods and simplifying cleanup. Additionally, liners can help distribute heat more evenly, reducing the risk of burning or uneven cooking. Some liners, like silicone mats, can also be reused multiple times, making them an eco-friendly option.
