Can I use recycled aluminum foil facing in cooking?

No, it is not recommended to use recycled aluminum foil for cooking. Recycled aluminum foil may contain impurities, contaminants, or have been exposed to chemicals that could be harmful when heated. Additionally, the quality and safety of recycled materials are often not as strictly controlled as new materials, which could lead to potential health risks. It's always best to use new, high-quality aluminum foil for cooking to ensure food safety and hygiene.
