Does it matter which side of aluminum foil is up?

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.

Which side is the nonstick side of aluminum foil?

When it comes to nonstick foil, the dull side (nonstick side) should be the side that actually touches food.

Does the shiny side of aluminum foil go on the outside?

Reynold's Kitchen, an aluminium foil manufacturer since 1947, says: "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." It's simply a result of the manufacturing process. The performance of the foil is the same, whichever side you use.

Why is Aluminum Foil Shiny on One Side But Not the Other?

Why is it advisable not to wrap potatoes in foil while baking?

NEVER BAKE POTATOES IN FOIL.

Do baked potatoes cook faster with or without foil?

Wrapping potatoes in foil does not hasten baking. On the contrary, since the foil itself has to be heated before the potato begins to bake, cooking times increase slightly. Not only do you get better baked potatoes when you bake them unwrapped, you also save money.
