If you’ve ever used aluminum foil before, you know one side of the foil is shiny and the other side is matte. In my household, the “right” way to use foil — shiny side-up or shiny side-down — is the subject of much debate. (My vote is shiny side-up.)
As it turns out, we’re not the only ones who have spent time thinking about this. There’s a lot of speculation on the internet, where different theories abound. I admit that I fell down the rabbit hole of considering different kinds of heat, the possibility of a coating, and clever marketing gimmicks before I finally landed on a reliable source, the Reynolds Kitchens website, and got an answer.
