Yes, you can use aluminum foil facing to wrap food for grilling. The shiny side of aluminum foil is non-stick and is safe for use with food. It helps prevent food from sticking to the foil and allows for even cooking. However, ensure that the foil does not come into direct contact with the heat source as it may cause the foil to tear or burn, potentially releasing aluminum particles into the food. Always follow grilling guidelines and safety precautions to avoid any risks.
