It is easy to be mistaken a flan as a custard.
No, a custard from a flan. Actually, a flan is a kind of custard which is probably the most famous and widely adapted custard dessert in the world.
According to The Food Timeline, it is important to note that custard was not unique to Europe. Similar recipes flourished in Asia.
As for the history of Custard started way back in the Ancient Romans. They're cooks recognized the binding properties of eggs. They were experts at creating several egg-based dishes, most notably patinae, crustades and omlettes. These foods were either savory (made with cheese, meat, pepper etc.) or sweet (flavored with honey, nuts, cinnamon etc.). Food historians generally agree that custard, the sweet almost pudding-like substance the Americans know today, dates to the Middle ages. At that time custard was eaten alone or used as fillings for pies, tarts, pastry, etc.
And then there's "Creme Caramel"...
It is the European counter part of baked custard. It originates in France. A light egg custard that is baked in a caramel-lined mould in a water bath. After the custard is baked, it is chilled and then turned out of the mold....In Spain, it is called flan and in Italy, crema caramella."
