According to Belgian lore, the villagers of the Meuse Valley would eat fish they caught in the river. In the cold winters, fishing became impossible, and villagers had to find other sources of nourishment.This is when they turned to potatoes, a popular root plant, and began preparing them exactly how they would cook fish, slicing and then frying them.A 19th-century manuscript by then-US President Thomas Jefferson mentions a dish called ‘Pommes de Terre Frites en Petites tranches’ (Potatoes deep-fried while raw, in small slices). Some historians claim that the original recipe was developed by a French chef called Honoré Julien.
