A word of caution: Do not use foil to wrap foods that contain acidic ingredients, such as tomatoes. Acid reacts with the aluminum foil, giving the food an off flavor.

The plastic wrap will prevent the reaction between the foil and the food during storage. The foil can be used as a cover when heating; remove the plastic wrap before heating.
