Can I use recycled aluminum foil facing for cooking or baking?

Recycled aluminum foil facing is not recommended for cooking or baking. While aluminum foil itself is safe for cooking and can be used to cover dishes or line baking sheets, recycled foil may have impurities or contaminants from previous uses. It may also be thinner and less durable, leading to potential tearing or puncturing, which can result in food contamination. For safety and food quality, it's best to use new, high-quality aluminum foil for cooking and baking.
