Quite simply, it doesn't matter what side of aluminum folk you use. Either is acceptable. Since the exact same material makes up both sides, they will perform precisely the same way. The only difference is aesthetic.
The difference in appearance between the dull and shiny sides of aluminum foil is a result of the manufacturing process. During production, aluminum is rolled out into thin sheets, and the dull side is the one that comes into contact with the highly polished steel rollers.
The non-stick side is the side with the dull or flat finish. To help indicate which side is non-stick the foil has been imprinted with the words "NON-STICK Side."
A: The matte side is where you would apply the color or lightener. The shiny side always faces out, to help warm up the foils.
According to Reynolds, which has been making aluminum foil for more than 75 years, both sides are OK to cook on. 1 “With standard and heavy-duty foil, it's perfectly fine to place your food on either side so you can decide if you prefer to have the shiny or dull side facing out,” Reynolds indicates on its website.
Shiny side up. Your vehicle hasn't flipped over after a rollover or accident. “Keep the shiny side up” means to have a safe trip.
Tin foil is stiffer than aluminum foil. It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminum and other materials for wrapping food.
Unless you're using a non-stick aluminum foil, it makes no difference which side of the foil you use. According to Reynolds, it's fine to place food on both the dull and shiny side of aluminum foil.
What is aluminum foil? Aluminum foil is a thinly rolled sheet of aluminum that has claimed its place as a common kitchen staple. Generally, using aluminum foil in the oven is safe, offering efficient heat conduction and simplifying cleanup.
Yes, foil on the window will reflect the heat of the sun away from the house and save energy on air conditioning. Taping aluminum foil shiny side out, to the outside of the window glass would probably reflect more heat away, keeping the inside cooler, since convective cooling would cool the foil somewhat.
Does the Shiny Side of Aluminum Foil Reflect More Heat? Aluminum foil reflects heat from both its dull and shiny sides equally. While aluminum foil has a dull and shiny side, there is no difference in how either side reflects heat.
The Risk Of Bacteria Growth
The Centers for Disease Control (CDC) warns that the presence of air can help potentially dangerous bacteria such as staphylococcus (staph) and Bacillus cereus, which can thrive in the conditions created by tinfoil storage, grow faster.
Donkey – Something at the rear side of the truck. Front door – Something is in front of the truck. Greasy – A slippery or icy part of the road.
Either side of the foil can be used to place food on, unless you are using Bacofoil® The Non-Stick Kitchen Foil, then the food should be placed on the non shiny side side, as this is the side that is coated with a food safe silicon to stop food from sticking.
Cage: a car, truck or van. Cager: person in a car, truck or van. Carbs: the carburettor, which supplies your bike's engine with the air and fuel mixture it needs to fuel your motorcycle.
Foil does not completely seal the food from air, which allows bacteria to grow faster. Some bacteria, like staph, can make toxins which are not killed when food is cooked. Bacteria can grow on the food and cause foodborne illnesses.
In short, science says it makes no difference at all, and there is no correct or incorrect way to use aluminium foil, as confirmed by Robert L. Wolke in What Einstein Told His Cook and America's Test Kitchen. You can place either side in either direction whether cooking or freezing food with aluminium foil.
Do not ever use parchment or wax paper in the broiler. Despite its heat resistance, parchment paper can't handle the heat of any broiler, which can reach temperatures upward of 500°F. And wax paper? It should never come near the high heat of the oven or broiler.

The paper won't release noxious chemicals, and will not burn. Most parchment paper is rated for use at temperatures no higher than 420 to 450 degrees. But we occasionally recommend using this liner for bread and pizza baked as high as 500 degrees.
