Is the shiny side supposed to be facing up with the food on it, or does it not matter, and if it does not matter, why is there a shiny side at all???

ive asked my twitter followers. will get back to you.

No, it's shiny side up and facing outwards when you wear the hat.

no response. foiled again.

oo oo. allegedly it doesn't matter. apparently one side gets polished as it comes off the rollers during manufacturing.

Boom boom, I was hoping for an 'aluminating' answer .........

That doesnt sound right to me, how can one side be THAT polished as just an incidental part of the process?  Im going to google it and find out ......

Hmm, apparently they were right, it is part of the process .... well I'll be darned.

Interestingly the shiny side has 88% reflectivity whereas the dull side has 80% reflectivity so presumably its better to have the shiny side up ......

somebody else says the shiny should be on the outside to keep the heat in. like for runners.

27/02/2013 at 09:21
I would have thought that the shiny side will reflect more heat at the bottom of the grill pan/barbecue etc. than the dull side. In the grand scheme of life I doubt if it makes a great deal of difference.

If using in cooking shiny side to food. Shiny side reflects so you want it reflecting heat back into the food not away from it. Cooks much better.
For your hat shiny side out as its better at reflecting the mind control rays - I like to use a double layer with a shiny side in as well - helps prevent mind reading........

Funny, I was wondering this only a few minutes ago as I put some chicken in the oven - I went for shiny side up, no particular reason. The packaging doesn't say either way but apparently our "One" kitchen foil donates 100% of profits to fund smokeless stoves in Africa. But what if they want to do kippers??

Simple, if it was shiny both sides, or Matt both sides, the sides would stick together on the roll and you would never unroll it, as it is Matt cant stick to shiny.

For those with no idea...  metal sheet is rolled between big shiny rolls, like being squeezed through a mangle.

This is standard practice for rolling of all sorts of metal sheets, but when it gets ultra thin, it creates problems, because the gap between the rolls is so small, and the loads get high, which flexes the big rolls.   In Aluminium foil, this problem is overcome by doubling it up....  having 2 separates sheets going through the roll gap at the same time, so the rolls feel like they are rolling aluminium that is twice as thick.  Both are squeezed thinner.  They put a liquid between them to make sure they don't fuse together.... so that when they come out of the other side of the mangle, they easily separate, and you have 2 thin sheets of foil.  The side which were squashed against the other aluminium foil come out a bit matt... and the sides that were directly in contact with the shiny roll come out shiny.

Correct.

Who would have thought the running community would have such intimate knowledge of the production of aluminium foil!

I am sorry to admit I found this genuinely interesting.

But why is Peter Everitt putting chicken in the oven at 9 in the morning?
27/02/2013 at 14:21
Maybe he's wants to cook it to eat.

Is it wrong to eat chicken in the morning? If not then it makes perfect sense to cook it first and an oven is a great tool for doing just that.
