aluminum foil
 

Is there any difference of which side you use aluminum foil? I usually use the shiny side. I heard theres no difference its the way it comes off the machine at the factory.
Are there any benefits with cooking on the dull side?

i was told that the shiny side toward the food keeps the heat inside as it reflects it back to the food. no scientific evidence just have always done it that way since i was young.

I was told the same thing pdcakm and I always use it that way.

I don't know about it cooking wise- but I am a Hairstylist and when we foil weave a highlight, there is no difference at all.

I was told,don't know when or by who, but I put the shiny side OUT.

I was told shiny side out conducts more of the heat. I just use it. Mr. Reynolds is a permanent resident in my kitchen cabinet. I hate doing dishes. I have been know to rinse/clean the foil for the recycling bin. Just put into another piece of recyclable material such as a beer box that has been flattened and they can see the foil.

I have never given it a thought. I just use it. If I cover a dish with it, I put the shiny side out because it is prettier. How's that for scientific logic?

According to the Reynolds Wrap people it does not matter which side is in or out. My Pop's and step Mom got into this ''discussion'' and he says It's like the dang toilet paper roll '''It don't matter which way it comes off the roll it still does it's job '''

Same here - shiny out.
