Which foil side

However, when measured over time in high temperatures, the difference is so slight that there should be little discernable change in cooking times. This may seem like a lot of explanation to come to the same conclusion, but it is not my purpose to give inaccurate explanations!

There are three basic ways heat can be transferred: conduction, convection , and radiation. Conduction is when heat is transferred through contact of one object with another hot object. This is what happens when we cook on the stove.

Convection is the transfer of heat by the physical movement of the surrounding fluid liquid or gas. Radiation is light waves, radio waves, microwaves, X-rays, etc. Any object with a temperature above absolute zero emits infrared radiation. This means that the heated coils, sides, and racks in your oven are emitting infrared energy. Even the heated vessel and the heated food itself emits this energy. However, when you cook food in an oven, the major source of cooking heat is convection.

The hot air of the oven transfers heat to the food being cooked. Only a little of the heat transfer in an oven is through infrared radiation, which is invisible light rays. A shiny surface should make no difference to convection but it will make a difference to radiation. Shiny surfaces reflect waves more than dull surfaces.

The reason one side of the foil is shinier than the other is because it is smoother and has fewer little imperfections: hills and valleys. So, the shiny surface of the foil should reflect more radiation than the dull surface, which will be better able to trap incoming waves rather than reflect them back.

We mill two layers in contact with each other at the same time, because if we didn't, the foil would break during the milling process. Where the foil is in contact with another layer, that's the "dull" side. The "shiny" side is the side milled without being in contact with another sheet of metal. The performance of the foil is the same, whichever side you use. One quick caveat though: If you are using non-stick foil , you definitely want to make sure to use the dull side, since only one side has the non-stick coating applied.
