When you line a baking sheet or wrap veggies to roast with aluminum foil, do you ever wonder which side to use, shiny or dull? Does it really make a difference in the end result?
No, is the answer! According to Reynolds, the difference results in the manufacturing process. During milling, heat and tension are applied to shape the foil into sheets. During the final step, two sheets are pressed together to provide strength. The side that comes in contact with the rollers becomes shiny, the other dull. So no need to be concerned with which side you are using.
NOTE: If you have purchased NON- STICK foil, make sure you use the side labeled "non-stick" - it will make a difference! There is an additional coating added when milling.
