The fried potato stick was born on the bridges of Paris in 1789.
In order to offer another product that could be easily consumed while walking down the street, doughnut sellers had the idea of dipping the satisfying tuber in frying after having cut it lengthwise, inspired by the elongated shape of the oldest bridge in Paris.
These "Pont-Neuf potatos" were immediately very popular and even inspired the songwriters and novelists of the time who simply renamed them "frites", a word that evokes both the way the potatoes were cooked and the way they were cut into strips.
You now know why English-speaking countries call this accompaniment to their dishes "French fries".
