Foil, Shiny side inside or outside?

[RedViking]

No googling. Only what your mamma told you. When cooking with aluminium foil, must the shiny side be inside or on the outside?

Preferably without the fork.

Depends what you are trying to achieve. Food cooked with shiny side in receives more radiant heat and shininess. If you compare roast beef cooked shiny side in and out, one clearly shines brighter.

Could have foiled me.

I am being debated every time I braai snoek, everyone knows better, but I like to braai my snoek 'neat' on the grid, so others best wear the foil.

As 3WA says. It depends on what you are trying to achieve.

Only real use for foil is for @rvZA 's hat, so ask him.

My beef says “silver side” on the label so i follow the instructions.

This thread is for the proper use of foil before the roast.

You should not be cooking with tinfoil. It's toxic.

Shiny side in, always

I didn't realize people eat tinfoil

Capd's a tinfoil expert I'd go with what he says.

It makes absolutely no difference.

It has a shiny and dull side because of the manufacturing process.

I remember this from way back. Our resident chef @DJ still shared it with us.

Should You Use Aluminum Foil With The Shiny Side Up Or Down?

It actually doesn't matter—here's the simple explanation for aluminum foil and the difference between its shiny and not shiny side appearances.

The difference is a byproduct of the manufacturing process. You see, aluminum foil is milled in different layers. Heat and tension are applied to stretch the foil until it's thin enough to become the familiar sheets you buy in stores and use at home.

The factory manufactures two sheets of metal simultaneously to ensure the sheets are strong enough to withstand breakage. The side where the foil comes into contact with another layer of foil appears dull, while the other side, which hasn't made contact with another sheet, appears shiny. In other words, the two sides look different, but when it comes down to it, they're both made of the same stuff.

So, now that you know the reason behind the different appearances of the two sides, you're probably wondering if you should use aluminum foil with the shiny side up or down. Quite simply, it doesn't matter.

Since the exact same material makes up both sides, they will perform precisely the same way. The only difference is aesthetic. So feel free to work both ways. In the end, your food will cook the same. Mystery solved.

Makes no difference other than in your mind.

It's no surprise you would confuse being cultured with tinfoil hattery.

Doesn't really matter

Shiny outside always, thats the way its rolled. There’s no other way.

There's a non shiny side?
