The Reason Aluminum Foil Has Both A Shiny And Dull Side
By Julia Mullaney
Aluminum foil is ideal for preserving food freshness, preventing oven messes, and cleaning grill grates, but you may be wondering which side to use for each task.
The choice of the shiny and dull sides is merely aesthetic. There's no functional difference, and the distinction arises from the manufacturing process rather than performance.
Reynolds, an aluminum foil brand, reveals that the dull side only looks like that because it comes in contact with another sheet of foil in the milling process.
The company stresses that it makes no difference in terms of product quality, stating, "It's perfectly fine to place your food on either side."
