best blanket for temperatures below freezing?
I was always told that it's best to have the shiny side towards the food, because the shininess reflects the heat and apparently helps to stop your grub getting burnt on one side and not on the otherHence the reason why the heat-proof suits which scientists wear when walking inside volcanos are shiny on the outsideOf course it doesn't really make any difference since the advent of fan-assisted ovens, which circulate the heat all around the food.
I don't think it makes any differencealuminum foil transfers teh heat regardless of which side is facing outthe easy way to test is to hold a match/lighter under the foil with a thermometer above ittry it with both sides down, and see if it makes a difthe shiny side isn't going to reflect heat, the foil transfers it too easily/quickly to make a difference.
Which side of Reynolds Wrap? Aluminum Foil should I use, the shiny or the dull side? Actually, it makes no difference which side of the aluminum foil you use—both sides do the same fine job of cooking, freezing and storing foodThe difference in appearance between dull and shiny is due to the foil manufacturing processIn the final rolling step, two layers of foil are passed through the rolling mill at the same timeThe side coming in contact with the mill's highly polished steel rollers becomes shinyThe other side, not coming in contact with the heavy rollers, comes out with a dull or matte finishThe exception is when using Reynolds Wrap? Release? Non-Stick Aluminum FoilThe non-stick coating is applied during manufacturing to the dull side of the foilAlways place the non-stick (dull) side toward the food.
