Some plain croissants are straight, while others are curved with their ends almost touching each other in the shape of a crescent moon.
The shape of a croissant – straight or curved — reflects the ingredients inside. At least, in France it does.
In France, it is the law that only a croissant made with pure butter can be straight. If a croissant is made with any other sort of fat, like margarine for example, it must be joined at the ends to form a crescent-moon shape.
Do you prefer straight or crescent-shaped croissants?
