Reynold’s Kitchen, an aluminium foil manufacturer since 1947, says: “It’s perfectly fine to place your food on either side so you can decide if you prefer to have the shiny or dull side facing out.” It’s simply a result of the manufacturing process. The performance of the foil is the same, whichever side you use.

Does the shiny side of aluminum foil reflect heat?

The reflective surface will reflect heat and the matte side will reflect less heat . If you’re baking or defrosting, the matte side will absorb more radiant heat and reflect less infrared heat while the shiny side will reflect more of both, so it makes more sense to bake and defrost with the matte side facing up.

What is the aluminum foil trick?
