Editor's note: Highly challenging to make at home, the secret to a divine croissant is the perfect marriage—close but not too clingy—between the dough and the butter. If they meld too much, that tight bond means loss of flakiness. So, love each other while maintaining your independence, and one of you needs to run out to the French bakery on weekend mornings while the other stays in bed drooling over gorgeous Croissant wallpapers!
