I am looking for a white cupcake tin or liner, I am not sure which you would call it, it looks like a Italian ice cup. Does anyone know where I can find it?
I think you might be looking for a nut or candy cup. They are plain white with pleats on the side and a rolled top? You can order them at any online store that sells candy supplies. I have even seen them in my grocery store. So, look for nut/candy cups and that should work
can you bake in them?
Sure! I see pics of cupcakes in those cups all the time. I think they are really popular in Australia or the UK because, when I look on flickr, a lot of the fancy cupcake "designers" use them (and they always seem to be from Europe/Australia).
