French Fries Origin

According to Belgian folklore, poor villagers used to fry fish they caught in the river, but when the river froze during the winter months, they needed other food alternatives.

They resorted to slicing potatoes and frying them the same way they fried fish, and the fried potatoes quickly became a delicacy.


During World War I, American soldiers stationed in Belgium were introduced to the fries, who then introduced them to the rest of the world.

Today, French fries are a popular side dish known worldwide. There are different varieties available, including traditional chips, wedges, curly fries, steak fries, waffle cut fries, and stick fries, also known as straight batonnet.
