First you (and by you I mean our baker-chocolatier Annie) make vegan croissants with no palm oil because palm oil kills everything good in this universe. Then you save a few for yourself for breakfast and grind the rest up, mix them with homemade butterscotch caramel. Mix until it's perfectly smooth, pipe into a chocolate shell and there you are: croissant as allegory for croissant. The metonym of metonymy, the croissant stands for a croissant and also is a croissant. (Or: isn't.) And also: The smile that is a croissant becomes the smile that tastes like a croissant: a smile simile.
You can get deep.
