From puff-pastry? Esp., with an apple filling, for example, (good) danish.

Puff pastry is made by folding and refolding dough, putting butter inbetween the layers. These layers multiply geometrically until, in the end, there are up to several thousand of them. The folding must be done carefully and neatly, or else the butter will run through and spoil the dough. Thus a French apple pastry, or pie(?), might be a confection involving neat folds, like neatly folded linens.
