Flan

The first references to a dessert resembling this one date back to the Romans, who made a dish known as Tyropatinam, using eggs, milk, and honey. Later, in the Middle Ages, there was a dish called "flado," which also had savory versions and would eventually become the flan or crème caramel we know today. It is one of Spain's most popular desserts, and was also exported to America. In France, there is a dessert called "creme renversée au caramel," whose name describes the concept perfectly: a cream that is inverted (removed from a mold and turned upside down) and served with caramel.
