Which side should come in contact with the foods? The shiny or the dull one?
This is a question frequently asked by consumers. Actually, both sides equally share the aluminum foil properties without any impact on the foods or your health, regardless of the side you use. Just don’t forget that no side of the foil should come in direct contact with acidic or salty foods. However, in the case of the non-stick foil, the right side to come in contact with foods is the dull one. It doesn’t matter if the food is acidic or salty, as the non-stick layer acts as a protection shield against corrosion.
