Fries are popular throughout the world thanks to ready-to-eat restaurants such as McDonald's and Burger King. In the early 1950s, the Jack Simplot, which had a company called JR Simplot, created the raw material for french fries in the form of peeled and frozen potatoes. Before the JR Simplot company supplies raw materials for fried potatoes, potatoes need to be manually peeled and cut into all McDonald's branches. JR Simplot frozen potatoes managed to shorten food preparation time and helped drive McDonald's franchise expansion.
French fries means "French-style fries." In English, the word fry can actually mean frying with a little oil (sauté) or frying in a lot of cooking oil until it is submerged (deep frying). Whereas in French, frire only means frying in a lot of cooking oil until it is submerged. Initially the verb "to french" was used to cut something in the form of a long match like a matchstick called Julienne-cut. According to the Oxford English Dictionary, the term "to french" is used for meat that is cut into small pieces, but this term has only been used after French fried potatoes are known to many people.
Belgian people claim that French fries are from Belgium, although this claim is not supported by strong evidence. Belgian people like to eat fried potatoes. In 2002, the average Belgian spent €6.01 to buy fries, including fried potatoes purchased at fast food restaurants. The Belgian historian Jo Gerard states that the recipe for french fries has existed in Belgium since 1680. At that time, poor people in the River Meuse valley between Dinant and Liège had a habit of eating fried small fish. In winter when fish are not available because of the frozen river, they fry potatoes that are cut into equal lengths.
In 1857, the newspaper "Courrier de Verviers" published an article about a Belgian businessman named Fritz who sold fries at the fair and dubbed him "king of fries". In 1862, the "Max en Fritz" fries outlet was established in the city of Antwerp, in a location close to Het Steen.
According to the Belgian story, the British army who came to Belgium during World War I had tasted Belgian-made fries and named it "French" because at that time French was the official language in the Belgian army. Fries are usually fried until submerged in liquid cooking oil or solid cooking oil at a temperature of 190°C until the surface of the potato is golden yellow and slightly crisp.
Some recipe books require that potatoes be fried twice in cooking oil, which is different in temperature. Potatoes are fried first in cooking oil at 177°C and removed when the potatoes are nearly cooked but still soft and pale. After being allowed to cool for a few moments, the potatoes are fried again briefly (not up to 1 minute) in cooking oil at 190°C until golden yellow and crisp.
