What does this actually mean?

[nomoss]

I notice that on a roll of papier cuisson, which looks to me like what is known in the UK as greaseproof paper, is written "utilisable des deux côtés"

I can translate this as "usable on both sides", that doesn't really make sense - I can use a sheet of writing paper on both sides, but I don't see how I can use both sides of a piece of cooking paper.

Does it mean "usable on either side", or is it an idiom meaning something else?

If it still looks serviceable after the first use, just turn it over and use it again. That's what we do, anyway.

Same as Alan.  We will often use one single sheet several times before it begins to brown.

Thank you both for the hints on paper economy[:)]

Yes, I would say it meant to use either side and perhaps I would.

If you fancy economy, I started buying these years ago and have had some for literally 15 odd years. I have cut some to size for my various baking tins and trays. They wash easily in warm soapy water.

I'm now wondering if they do double-sided toilet paper?

That would solve a lot of current problems[:D]

Maybe my question was already answered

But you really need Bronco for this.

Which, if my memory serves me correctly, was much the same as grease-proof paper.

[idun]

At a limit I could use grease proof paper twice, but no more, cakes can slightly stick to it, and I wouldn't fancy trying to wash it.

I rarely use it more than once anyway, and usually only when it has pastries or scones on it. Would depend.

And the talk of Izal or Bronco, honestly, very bad memories and one would have to sing 'happy birthday' several times whilst hand washing to get the 'stink' off that off one's hands.[:-))]

Some such paper is, I believe, supplied with a usable side and an unusable side.  The difference being detectable by texture or sheen.  Your paper doesn't appear to fall into that category hence useable on either side.
