Aluminum Foil

While many believe that the different properties keep heat out when wrapped with the matte finish facing out, and keep heat in with the matte finish facing inwards, the actual difference is imperceptible without instrumentation.

Its just part of the proccess used to create the foil.

"The shiny side is produced when the aluminium is rolled during the final pass"

So which side keeps in more moisture? This could be the cause of many a runny lasagna.

try poking some holes in the foil during the last 15-20min of your baked pasta it will let the excess moisture out, or take off the foil for the whole cooking process and have the cheese all browned up.

maybe the tomato sauce is not reduced enough ??

ok this is getting side tracked, sorry to highjack.

Fishward has it correct.... When cooking, its not like you are putting in the sunshine and has nothing to do with conductivity.

The Foil will get hot and keep heat in, no matter what side you use.

HEHE, great thread though.

Umm.. The whole foil discussion is well over with, we've all moved on to bigger and better things in this thread, like tums?!?

actualy tums don't contain AL, but some of the more powerfull antacids do.
