In Belgium, fries are traditionally served in a cone. The familiar container is called a cornet de frites in French and a frietzak or patatzak in Dutch. It is usually made from white paper or light cardboard, allowing vendors to hold a generous portion while leaving the top open for sauces such as mayonnaise.
This serving style is closely associated with Belgian friteries, specialized fry shops found throughout the country. The cone is practical as well as distinctive: its narrow base makes it easy to carry, while the wide opening provides room for fries and toppings. Some vendors place the cone inside a small tray or wrap it in an additional sheet of paper, but the cone remains the traditional shape.
A common mix-up is assuming that “French fries” must have originated in France. Belgium has a strong national fry culture and widely treats frites as a signature food. The paper cone is therefore a serving tradition, not a description of how the potatoes are cut or fried.
