Aluminum Foil
Description
Aluminum foil, also known as aluminium foil outside of North America, is a versatile kitchen ingredient known for its ability to conduct heat, resist moisture and odors, and provide an airtight seal. It's a thin sheet of aluminum metal, typically measured in gauges or microns, that has become an essential tool in food preparation, storage, and preservation. Aluminum foil is used globally and comes in various sizes, with measurements often given in inches or centimeters and thickness in millimeters or mils. The convenience and functionality of aluminum foil make it a valuable addition to any kitchen, whether you're an amateur cook or a professional chef.
Common uses
Aluminum foil is commonly used for wrapping food items to maintain their freshness, preparing packets for grilling or baking, lining baking sheets or pans to prevent sticking, and covering dishes to retain heat. It is also used for packaging food for storage or transport.
