French fries are served hot, either soft or crispy, and are generally eaten as part of lunch or dinner or by themselves as a snack, and they commonly appear on the menus of fast food restaurants. Fries in America are generally salted and are often served with ketchup; in many countries they are topped instead with other condiments or toppings, including vinegar, mayonnaise, or other local specialties. Fries can be topped more heavily, as in the dishes of poutine and chili cheese fries. French fries can be made from sweet potatoes instead of potatoes. A baked variant of the french fry uses less or even no oil.
Despite its name, the French fry is not French. The origins of the French fry have been traced back to Belgium, where historians claim potatoes were being fried in the late-1600s. According to local Belgian lore, poor villagers living in Meuse Valley often ate small fried fish they caught in the river.
