Oh blast! I knew the answer to the original question, but didn't even look at the thread as I thought the scraper in question is the kind you use on a car windscreen to get rid of frost - and I don't know what THAt is called.
Une spatule or une maryse (if you watch loads of cookery programmes you will know) but as usual, Clair knew it and was so much faster on her keyboard.
Now, could anyone tell the name of the scraper for car windscreen/window? Or has it been said earlier and I have missed it?
