Which side of the aluminium foil should be on the outside when putting something in the oven - dull or shiny?

Answer 1

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 food. The difference in appearance between dull and shiny is due to the foil manufacturing process. In the final rolling step, two layers of foil are passed through the rolling mill at the same time. The side coming in contact with the mill's highly polished steel rollers becomes shiny. The other side, not coming in contact with the heavy rollers, comes out with a dull or matte finish.

The exception is when using Reynolds Wrap® Release® Non-Stick Aluminum Foil. The non-stick coating is applied during manufacturing to the dull side of the foil. Always place the non-stick (dull) side toward the food.

Answer 3

dull side out beacuse it will absorb the heat and the shiny side doesn't stick to the food. THe heat will go inside the aluminum and the heat will keep bouncing off the shiny side into the food.

Good luck!

Answer 4

At my restaurant I wrap bakers shiny side in and I wrap sweet potatoes shiny side out because spuds take longer to cook and the shiny side reflects more heat back this way I can put them all in the oven at the same time.

Answer 5

The shiny side on the inside it gives a better colour to your food when cooking.
The dull side is for preventing heat to penetrate inside and also protects from freezer burns.

Answer 6

The shiny side should be facing down so your food is against the dull side. This way the food won't stick.

Answer 7

I don't know if it matters, but if I am using it to line the baking sheet, I put it shiny side up, so that it helps the food (like french fries) get crispier. I don't know if it matters if you're covering the top of something.

Ha ha, it could just be my imagination that it makes the french fries get crispier...

Answer 8

depends on what u r baking shiny holds the heat where the dull side doesn't hold it as hot as the shiny but if you forget its OK it will be fine.

Answer 9

The dull side should be on the outside.

Answer 10

No- it depends what you want to have happen. The shinny side will reflect a little more heat. If you want that heat directed at the food, like for a nice roast, then point it to the food. If you want the ambient heat to be more constant, and the direct heat to be less strong, like for a casarole- send the shine outside.
