Aluminum Foil sides
So I actually never heard about this before joining this forum; why do people say to put the shiny side of the foil down? There is no difference in manufacturing. The sheets get made in pairs, and get stacked as they go through the flattener. So, the side of the foil to touch the flattener gets shiny, the other side is dull. There's no chemical difference.
So am I missing something when everyone says to put the shiny side down? Or is it just superstition/people not knowing how these things are made?
