History

Interestingly, in the later 19th and early 20th century, tin foils were in common use, due to which some people still call aluminum foils as tin foils. The reason why tin foil was replaced by aluminum was because, tin gave the food item a distinctive metal flavor, which aluminum did not.
In the year 1910, in Switzerland, it was used as a protective barrier between the food and tin, and was introduced to the US in 1912, by wrapping Life Savors (American mint) and other candy bars in it.

Along with wrapping cooked food, this foil is also used while cooking. The best use while cooking is done for making BBQ recipes and especially delicate food items like mushrooms and other such vegetables. You can easily learn how to grill vegetables in foil and enjoy better tasting food with less moisture loss.
Using this foil in microwave however, was a bit harmful in earlier days. The electric field of a microwave creates an opposite charge with the foil and causes sparks in some cases. Nonetheless, today, oven and microwave ovens are designed in a flexible way and one can use foil in them.
