Credit to Sara for discovering dough-in-a-can, and even more for daring to buy some (the croissant version). Apparently unique to mainland Europe and North America, croissant and bread-roll doughs are available here by the cardboard can. Like with all things, they don't quite compare with the "real thing" (i.e. those bought from a bakery), but at just over a single Euro for 6 pieces of deliciousness? Definitely gets my vote.
