Yes, aluminum foil can be used to wrap hot food. It is commonly used to keep food warm, cook food evenly, and prevent food from sticking to the cooking surface. Aluminum foil is heat resistant and can withstand temperatures up to 450掳F (232掳C). However, it's important to avoid wrapping food in aluminum foil at very high temperatures for extended periods, as this can lead to discoloration and potential health concerns. Always ensure that the foil is food-grade and in good condition to avoid any contamination.
