French fries, or simply fries (North American English), chips (British and Commonwealth English, Hiberno-English), finger chips (Indian English), or French-fried potatoes, are batonnet or allumette-cut deep-fried potatoes.
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 diners, fast food restaurants, pubs, and bars. They are usually salted and, depending on the country, may be served with ketchup, vinegar, mayonnaise, tomato sauce, or other local specialties. Fries can be topped more heavily, as in the dishes of poutine or chili cheese fries. Chips can be made from sweet potatoes instead of potatoes. A baked variant, oven chips, uses less oil or no oil.
French fries are prepared by first cutting the potato (peeled or unpeeled) into even strips, which are then wiped off or soaked in cold water to remove the surface starch, and thoroughly dried. They may then be fried in one or two stages. Chefs generally agree that the two-bath technique produces better results. Potatoes fresh out of the ground can have too high a water content—resulting in soggy fries—so preference is for those that have been stored for a while.
