Why can't I roast with wrapping foil?!

[DitaVonCheese]

I've bought Tesco Value "wrapping foil" because it was the cheapest tin foil. Just looked at the instructions and it says that it's just for wrapping and not for roasting. Why on earth not? I actually just want to use it to line a baking sheet - am I going to ruin our date night oven chips?

i think it's to do with high temp and salt content of food

I have been wrapping roast chicken in foil for years now - take it off after about half an hour. It always tastes lovely and no one I have fed it has died (yet). I had no idea this was not advised. Will watch with interest.

i think it's different grades of foil - wrapping foil might be a compound 'foil'...still googling..

Thanks Jane, I did do a bit of googling but couldn't find anything.

Spero I think roasting foil is fine, it's just this spurious "wrapping foil" ("for wrapping food only, not for roasting" or words to that effect) that I can't roast with. I suspect it's to make me buy two types of foil for no reason

I think it said it was aluminium foil on the pack

ah now ASDA have their 'wrapping foil' under 'plastic wrap' heading on their shopping website

Some of the cheapo stuff does stick to food/tin when it gets very hot so you may find yourself picking bits of tinfoil out of your dinner.

does this explain?

ignoring my shit reason

Dammit. This will teach me to be cheap frugal. I have got The Fear and decanted our chips into an oven dish.

I never knew there was such a thing as wrapping foil , until I bought some thinking it was just , well, foil.

That redirected me back to the Sainsbury's home page

oooer

it said "Sainsbury?s wrapping foil is a fine gauge foil and therefore not suitable for roasting."

Thanks - so it's just thinner but otherwise the same you think?

Usual - same here!

i think it's probably thinner so has a coating of some sort of plastic over it to make it more durable

i'm almost tempted to email a manufacturer to find out

no idea where DD gets her aspie traits from

I feel I've learned something and the chips (foil-free) were surprisingly good :)

It's just thinner.
And you can use it for roasting.
I do it all the time.
They just say that so that they don't undercut their own trade in thick expensive foil.

I never even guessed there were different grades of foil. Just as I never realised before tonight that you could buy different disposable nappies for boys and girls. Wonders never cease eh?

Can you Spero? I thought I had heard of such things, but then had DS and he kept peeing out the front while the back was still dry and looked for some but couldn't find any

Thanks Blu, will use my wrapping foil defiantly

Ah, I didn't think that such nappies would actually have any purpose, I thought it was just some marketing ploy like with razors - make 'em pink and double the price.

I had forgotten about boys bitz. (mother of one girl)
