About the article "French fries", section "Variants".

Candidate passages:
Variants of French fries include "thick-cut fries", "steak fries", "shoestring fries", "jojos", "crinkle fries", "curly fries", "hand-cut fries" and "tornado fries".
Fries cut into rough cubes instead of sticks are called "home fries".
Fries cut thickly with the skin left on are called "potato wedges", and fries without the skin are called "steak fries", essentially the American equivalent of the British "chip".
They can also be coated with breading, spices, or other ingredients, which include garlic powder, onion powder, black pepper, paprika, and salt to create "seasoned fries", cheese to create "cheese fries", or chili to create "chili fries".
Sometimes, French fries are cooked in the oven as a final step in the preparation (having been coated with oil during preparation at the factory): these are often sold frozen and are called "oven fries" or "oven chips".
Some restaurants and groceries in North America offer French fries made from sweet potatoes instead of traditional white potatoes.
In France, the thick-cut fries are called "Pommes Pont-Neuf" or simply "pommes frites", about 10 mm; thinner variants are "pommes allumettes" (matchstick potatoes), ±7 mm, and "pommes paille" (potato straws), 3–4 mm (roughly ⅜, ¼ and ⅛ inch respectively).
The two-bath technique is standard (Bocuse).
"Pommes gaufrettes" or "waffle fries" are not typical French fried potatoes, but actually crisps obtained by quarter-turning the potato before each next slide over a grater and deep-frying just once.
This results in large flat fries with two layers, each of which consists of parallel strips of potato.
In an interview, Burger King president Donald Smith said that his chain's fries are sprayed with a sugar solution shortly before being packaged and shipped to individual outlets.
The sugar caramelizes in the cooking fat, producing the golden color customers expect.
McDonald's was assumed to fry their fries for a total time of about 15 to 20 minutes, and with fries fried at least twice.
Chicken fries are chicken nuggets shaped like french fries. 
French fries (American English) or chips, fries, finger chips, or French-fried potatoes are batons of deep-fried potato.
Americans and most Canadians refer to any elongated pieces of fried potatoes as "fries", while in the United Kingdom, Australia, Ireland and New Zealand, long, thinly cut slices of fried potatoes are sometimes called "fries" to distinguish them from the more thickly cut strips called chips.
French fries are served hot and generally eaten as an accompaniment with lunch or dinner, or eaten as a snack, and they are a common fixture of fast food.
French fries are generally salted and, in their simplest and most common form, are served with ketchup; in many countries, though, they are topped instead with other condiments or toppings, including vinegar, mayonnaise, or other local specialities.
Fries can also be topped more elaborately, as is the case with the dishes of poutine and chili cheese fries.
Sometimes, fries are made with sweet potatoes instead of potatoes, are baked instead of fried, or are cut into unusual shapes, as is the case with curly fries, wavy fries, or tornado fries. 
There are many variants of the Murga punishment.

In Canada, French fries are the main component of a dish called "poutine", a mixture of French fries with fresh cheese curds, covered with a hot gravy (usually), hot chicken sauce (much less common), or chicken BBQ sauce (rarely).
This dish was invented in rural Quebec in the late 1950s and is now popular in many parts of the country and is served at many fast-food chains.
Several Québécois communities claim to be the birthplace of poutine.
A variant, "disco fries", may be found in the Northeastern United States.
In Newfoundland, "chips, dressing and gravy" (referred to by outsiders as "Newfie fries") comprise French fries topped with "dressing" (turkey stuffing made with summer savory) and gravy.
Another variation consists of topping the French fries with either ground beef, hot dogs, dressing and cheese and topped with gravy.
Yet another Newfoundland recipe called a "mess" (compare with "poutine") consists of fries, gravy, dressing, and wieners.
In Prince Edward Island, "fries with the works" (or FWTW as it is some times called) is a combination of French fries, fried hamburger, fried onions, gravy (usually beef), peas, and optionally mushrooms.
Other common toppings include green onions, tomatoes, carrots, sour cream, and grated cheese.
