Question:

What's the difference between the different sides of tin foil?

One side is shiny and one side isn'tI've read recipes that specifically say to use one side or the other.What is the difference??

Answer:

It doesn't matter what side you useThis was printed in the Washington PostHousehold aluminum foil is so thin (0.0005 of an inch) that the rollers can't handle it without tearing itThe final rolling is therefore done on a sandwich of two sheets, face to faceThe outer surfaces emerge with a finish as smooth as the rollers, while the two face-to-face inner surfaces emerge with a matte finishHence, a shiny side and a duller sideWhen you use the foil, it makes no difference which side is up, down or sideways.
