Is the shiny side of the aluminum foil safer to touch the food when heating or the dull side?

Answer 1

It is a result of the rolling process, manufacturers roll a large ingot of aluminum through successivly smaller thickness of roller so the ingot gets thinner and thiner, however for the very last roll the aluminum is to thin to be rolled alone, so they put through two sheets, the sides which face each other become dull.

Answer 2

You will be told:

1. You cook with the dull side out and the shiny in.
2. You cook with the shiny side out and the dull side in.

However, the manufacturer states unequivocally that:

• It does not matter.
• One side is dull from the manufacturing processes, that's all.

Answer 3

Both sides of the foil will be equally hot. The shiny side reflects heat and is better for lining a baking sheet when cooking something you want crisp like frozen french fries or fresh potato wedges. The dull side absorbs heat and is best for lining baking sheets for cookies or wrapping baked potatoes with dull outside.

Answer 4

It doesn't really matter if the shiny side of the foil is up or down. It is up it may reflect heat a little better than the dull side, but the basic function will remain the same.

Answer 5

You put the shiny side to where you want the heat. If it was shiny both sides it would not be as effective. Mudkipo, I will suck your dick.

Answer 6

if speaking of aluminum the shiny side should always be towards the food, it is the polished side .
