JFF: Foil--shiny Side up or Down?

Do you put the shiny side up or down?

My husband was making smores and it just about drove me mad to watch him put the dull side out. I had to bite my tongue from correcting him. Then, it got me thinking. Is there really a right or wrong way to it? Below is an answer I found from America's Test Kitchen. What other things drive you nuts if not done your way (ie toilet paper over the top or down the wall)?

According to Reynolds Consumer Products, during manufacturing, two layers of aluminum foil are passed through the rolling mill at the same time. The side that comes in contact with the rollers becomes shiny, and the other side emerges with a duller finish. But is there a difference in how the surfaces reflect heat that affects cooking?

Even in the test kitchen, some test cooks prefer cooking with the shiny side up, others the opposite. To settle the issue once and for all, we baked stuffed manicotti covered with foil shiny side up and shiny side down. A probe thermometer inserted in the center revealed that both casseroles reached the same temperature (within a couple of degrees) in the same amount of time. To test browning, we oven-baked bacon on foil-lined baking sheets. Shiny side and dull side produced crisp, golden-brown bacon within a few seconds of each other.

THE BOTTOM LINE: The shiny and dull sides of aluminum foil insulate and conduct heat at the same rate.

What can I do next?

I generally don't pay attention but a tid bit if you are dealing with solar heat it must be shiny side in. Yeah, in girl scouts we made ovens out of cardboard boxes and foil. The shiny side may conduct heat the same but it also repels solar heat, either that or I was lied to as a girl scout and my whole world is now crushed!

I don't pay attention. Whatever side ends up out is the side I go with. I hate cooking so much, I just throw the stuff on and walk away fast as I can!!

It doesn't really matter to me.
But I think, I tend to put shiny side facing out. If making foil pockets.
Who knows.
I don't think my Hubby even takes notice of which side is where. LOL

I know though, these things are but one of those daily irks huh?
I have many irks today.
Slap myself on the head.

good to know! i always use it as it comes out of the roll - shiny side up if covering a dish, which ends up inside if i am wrapping meat or what have you...but i always felt that the shiny side was "meant" to be on the outside. so i always kinda thought i was doing it "wrong" lol.

Good job! I've actually wondered about that.
You questioned your own beliefs and ended up learning something. I strive for that sort of thing, especially when raising kids.

What drives me nuts?
- when people add oil to the water when making pasta so it doesn't stick (try adding salt and stirring it a little)
- when people don't season their food so you can just add the amount of salt you want ... Thanks for the flavorless food :-)

Depends on how I'm using it. Like if I'm lining a cookie sheet I put shiny side up, but if I'm wrapping or covering something it would be shiny side out.

I always put shiny side up.

If someone else (husband, friend) did it the opposite way, I am sure I would notice, but I am not uptight about things like that. It's not like I'd tell them they're doing it wrong nor would I "fix" it when they're not looking.

oh yeah it bugs me, I feel like the shiny side shoud be in, logically, BUT i can't do it, it isn't pretty that way, so i just slap it on and try not to over think it because i can't do it logically.

Also it's how it comes off the roll. I flip the box so it rolls out to the right, which means andything i place on it touches the dull side..

way wya way overthinking this see.
