Oooh, you’re right! Forgot about that one. I wonder why they use it, now that you mention it.
It was originally made by the request of Louis XIV, who – in the context of Jean-Baptiste Colbert’s mercantilistic policies – was looking for a native French product to replace the then very popular Edam. To make it distinct from Edam he seasoned it with annatto to give it a sweet and nutty flavor and a distinct orange color.
