Silver foil has a shiny and dull side... when making a helmet to stop aliens trying to interfere with my brain the shiny side goes on the outside to bounce the voices back to space silly

BUT when cooking, which side should be on the outside ?

Doesn't matter. Just the manufacturing process.

My wife would be prepared to fight to the death to demand that the matt surface should face the food, but can not explain why, but hey if her mum does it that way it must be true, apparently.

If you get the non stick stuff the dull side is the cooking side.

Use the dull side. The shiny side reflects the heat.

What will you be wondering while you wander, I wonder?

The reason there is a shiny side and a dull side is due to the way it is rolled.

It's too thin to roll in a single sheet so in the final pass two layers are rolled together.

When the sheets are separated the shiny side is the side which was in contact with the rolls and the kerosene based lubricant, and the matte side is the side in contact with the other aluminium.

In theory, therefore, the matte side is the side to use in contact with the food on the basis of potentially less contamination, New Pod can now explain to Mrs New Pod that she and her mother are correct.

However when one considers how many operations and rolling passes, annealings and treatments and cleanings the foil has been through since in the form of a cast ingot Mrs Pod's correctness is moot.

I used foil with the shiny side out to cook a fish.

It was far from raw.

I don't really think it matters.

Both sides are quite reflective; the shiny side is slightly more reflective. For actual cooking it makes no difference as a tiny difference in reflection doesn't affect heat transfer sufficiently to make a difference. Bear in mind that most of the heat transfer in an oven is from conduction with the air, not radiated heat, and shininess only affects radiated heat.
