What is the best way to store food in aluminum foil facing?

The best way to store food in aluminum foil is to ensure that the dull side faces the food and the shiny side is on the outside. This is because the dull side is more heat resistant and less likely to contaminate the food with any potential chemicals from the foil. When wrapping food, seal the edges tightly to keep air and moisture out, which helps in preserving the freshness and quality of the food. Always use aluminum foil as a single-use item to avoid any potential transfer of bacteria or contaminants from previous uses.
