I have heard that to soften sugar paste to roll out for cutting letters I should be mixing it with some sort of powder - can someone please elaborate on this? I am in the UK
I haven't heard of softening sugarpaste to roll out. To the contrary, I add tylose, a white powder that stiffens it, making it easier to cut letters. Perhaps that is what you've heard? If I'm in error, I'm sure someone here will post and correct. There is a lot of knowledge out there.
