Wrap it Foil - heavy duty (350 x 50m)

Aluminum foil is commonly used for baking, cooking, and packaging food. However, the reflective and insulative properties of this material make it useful far beyond the kitchen. Think outside the box and make the most of each roll of aluminum foil!

Do not use aluminum foil in a microwave. Aluminum deflects the electromagnetic waves that cook food so efficiently in a microwave oven. This might cause your food to cook unevenly, and it might even damage the appliance. Remember: metal and microwaves do not mix!

Keep food warm or cold. Aluminum foil is a great insulator, meaning that it is great for keeping hot foods hot and cold foods cold. Use it to wrap leftovers or pack your lunch. Individually wrap each food item into a sheet of heavy-duty aluminum foil. Bend the foil into a "tent" shape, and fold the ends down tightly to trap heat. If you wrap your meal well, it should hold the same temperature for hours.

Preserve food with aluminum foil. Aluminum foil has the lowest moisture-vapor transfer rate of almost any wrapping material. This means that it is extraordinarily good at keeping food from drying out. Foil is also great for retaining the odor of smelly foods.  Wrap leftovers in an airtight seal of aluminum foil, then store in the freezer or refrigerator until you are ready to eat again.

• If you don't have access to a freezer or refrigerator, you can still use aluminum foil to keep food fresh. Store the wrapped-up food items in a cool, dark, dry place.
• Aluminum foil is even better than plastic wrap at retaining odor and moisture. Just make sure that you carefully seal each item so that it's as airtight as possible! This will make the food less prone to freezer burn.
