Which side of aluminum foil goes up?
According to Reynold’s Kitchen, the difference in appearance between the two sides of aluminum foil is simply a result of manufacturing and serves no real purpose. Meaning, whether you are cooking your food with the shiny side up or the dull side up, you’re doing it right.
Why does aluminum foil have two different sides?
The reason the two sides are different is because of the manufacturing process called tilling. However, when it comes to non-stick foil, there is a designated side, which is the dull side, as the non-stick coating is only applied to that side.
Which side of the aluminum foil do I use for baked potatoes?
Shiny side wins! Yes, if the shiny side is touching the potato, it will cook faster, so wrap it right! The shiny side cooks faster because it absorbs more radiation from the oven and reflects more radiation back into the potato due to the difference in emissivity between the shiny and dull sides of the aluminum foil.
Is it better to bake potatoes in foil?

Do you poke holes in foil when baking potatoes?
Poke holes in potato and wrap in foil. Bake in oven for 45 to 60 minutes until tender.
Why is aluminum foil shiny and dull?

Is aluminum foil made of pure aluminum?
Aluminum foil is made by rolling sheets of 98.5 percent pure aluminum metal between pairs of polished, lubricated steel rollers. Successive passes through the rollers squeeze the foil thinner. Household aluminum foil is so thin (0.0005 of an inch) that the rollers can’t handle it without tearing it.
Is salt water a solution?
You can let the water evaporate, and you will have just the salt left.
