Flan originated in Europe, with its roots tracing back to ancient Rome. The Romans created an early version of flan called "flado," a flat custard cake made from eggs, milk, and honey, which was initially savory and sometimes flavored with fish or meat. Over time, the recipe evolved into a sweet dessert, especially after the Spanish added caramelized sugar to it. The Spanish then brought flan to the Americas during the colonial period, where it became a popular dessert in Latin America, particularly in Mexico, Puerto Rico, and Cuba
. In summary, flan's origin is European, specifically from ancient Rome, and it was later refined in Spain before spreading to the Americas.
