This is the Saint–Honoré croque légumes à la fleur d’hibiscus confite from Ladurée in France. XXX veggie porn! It is a savory version of the classic St. Honore cakes that are flavored with things like raspberries, roses and chocolate.
According to the blog I got the picture from, there is savory whipped cream piped on top, kind of like creme fraiche. How insanely backward would it be to attempt a vegan version?
