Most people think it matters whether aluminum foil is used shiny side up or down, but the surprising truth is that it doesn’t make a difference. The variation is a result of the manufacturing process—the shiny side comes in contact with highly polished steel rollers, and the matte side doesn’t.
Moreover, is it safe to cook with aluminum foil in the oven?
As stated above, you most definitely can put aluminum foil in the oven (as long as you’re not coating the bottom of the oven itself). … To be on the safe side, use an alternative when possible, and at least avoid using foil when cooking at high temperatures or cooking acidic foods.
Beside this, is there a difference between the sides of aluminum foil?
“It makes no difference which side of the foil you use unless you’re using Reynolds Wrap Non-Stick Aluminum Foil.” Non-Stick foil actually has a protective coating on one side, so the company recommends only placing food on the side marked “non-stick” for maximum efficiency.
What side of foil do you bake potatoes on?
Shiny side wins!
The shiny side cooks faster because it absorbs more radiation from the oven and reflects more radiation back into the potato due to the difference in emissivity between the shiny and dull sides of the aluminum foil.
When it comes to nonstick foil, the dull side (nonstick side) should be the side that actually touches food.
The reason the two sides are different is because of the manufacturing process called tilling. However, when it comes to non-stick foil, there is a designated side, which is the dull side, as the non-stick coating is only applied to that side.
Experts at Reynold’s Kitchen say that the difference between the two sides is due to a manufacturing process called milling, during which heat and tension is applied to stretch and shape the foil. … “The ‘shiny’ side is the side milled without being in contact with another sheet of metal.
