Aluminum Foil: Is There A Right Or Wrong Side?

,
Gourmandize

You've probably noticed there's a dull side and the shiny side... So what's the difference?

Have you ever noticed how aluminum foil has two sides? Take a look: one side is dull, one is shiny! So which side should go up?

The answer is: it doesn't make a difference at all.

According to Reynolds, there is no right or wrong side to aluminum foil. But why are the two sides different? It's all about processing:

"This is a common question and the answer is that the foil is 'milled' in layers during production. Milling is a process whereby heat and tension is applied to stretch the foil to the desired thickness. We mill two layers in contact with each other at the same time, because if we didn’t, the foil would break during the milling process. Where the foil is in contact with another layer, that’s the 'dull' side. The 'shiny' side is the side milled without being in contact with another sheet of metal. The performance of the foil is the same, whichever side you use."

However, if you are using non-stick foil you should use the dull side, as that is the one with the non-stick finish. 

So there you have it. Now you can sleep soundly at night!
