Welcome to the I Can't Sleep Podcast, where I help you drift off one fact at a time. I'm your host, Benjamin Boster, and today's episode is about French fries. French fries, or simply fries, are also known as French fried potatoes, chips, and finger chips, or Batenet or Julian cut deep-fried potatoes of disputed origin. They are prepared by cutting potatoes into even strips, drying them and frying them, usually in a deep-friar.
Starting point is 00:01:50 Pre-cut blanched and frozen russet potatoes are widely used, and sometimes baked in a regular or convection oven, which is an air-friar. 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 typically salted and may be served with ketchup, vinegar, mayonnaise, tomato sauce, or other sauces. Fries can be topped more heavily, as in the dishes of putine, loaded fries, or chili cheese fries,
Starting point is 00:02:45 and are occasionally made from sweet potatoes instead of potatoes. The standard method for cooking French fries is deep frying, which submerges them in a hot fat, typically oil. The potatoes are prepared by first cutting them, peeled or unpeeled, into even straight. 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. In the two-stage or two-bath method, the first bath, sometimes, called blanching, is in hot
Starting point is 00:03:57 fat to cook the fries through. This step can be done in advance. Then they are more briefly fried and very hot fat to crisp the exterior. They are then placed in a colander or on a cloth to drain, then served. The exact times of the baths depend on the size of the fries. For example, for two to three millimeter strips, the first bath takes about three minutes, and the second bath takes only seconds. Since the 1960s, most French fries in the U.S. have been produced from frozen
Starting point is 00:04:43 russet potatoes, which have been blanched, or at least air-dried industrially. The usual fat for making French fries is vegetable oil. In the past, beef suet was recommended as superior,
Starting point is 00:05:00 with vegetable shortening as an alternative. McDonald's used a mixture of 93% beef tallow and 7% cottonseed oil until 1990 when they changed to vegetable oil with beef flavoring. French fries are fried in a two-step process. The first time is to cook the starch throughout the entire cut at low heat, and a second time is to create the golden, crispy exterior of the fry at a high temperature.
Starting point is 00:05:40 This is necessary because if the potato cuts are only fried once, the temperature would either be too hot, causing only the exterior to be cooked and not the inside, or not hot enough where the entire fry is cooked, but its crispy exterior will not develop. Although the potato cuts may be baked or steamed as a preparation method, This section will only focus on French fries made using frying oil. During the initial frying process, approximately 150 degrees Celsius,
Starting point is 00:06:21 water on the surface of the cuts evaporates off the surface, and the water inside the cuts gets absorbed by the starch granules, causing them to swell and produce the fluffy interior of the fry. The starch granules are able to retain the water and expand due to gelatinization. The water and heat break the glycosidic linkages between amylapectin and amylostrands, allowing a new gel matrix to form via hydrogen bonds, which aid in water retention. The moisture that gets trapped within the gel matrix is responsible for the fluffy interior. of the fry. The gelatinized starch molecules move towards the surface of the fries, forming a thick
Starting point is 00:07:19 layer of gelatinized starch, and this layer of pre-gelatinized starch becomes a crisp exterior after the potato cuts are fried for a second time. During the second frying process, approximately 180 degrees Celsius, the remaining water on the surface of the cuts evaporated. and the gelatinized starch molecules that collected towards a potato surface are cooked again, forming the crisp exterior. The golden brown color of the fry will develop when the amino acids and glucose on the exterior participate in a myelard browning reaction. In the United States and most of Canada, the term French fries or French fried potatoes,
Starting point is 00:08:17 sometimes capitalized as capital f french fries or shortened to fries refers to all dishes of fried elongated pieces of potatoes variants in shape and size may have names such as curly fries shoe string fries etc in great britain australia south africa ireland and new zealand The term chips is generally used, being a popular dish in most commonwealth countries. However, the term French fries or skinny fries is used for thinly cut fried potatoes, which are distinguished from the more traditional thick-cut chips. In the U.S. or Canada, these more thickly cut chips might be called steak fries, depending on the shape. While the word chips is more commonly used in North America to refer to potato chips,
Starting point is 00:09:28 commonly known in the UK, Ireland, and South Africa as crisps. In Australia and New Zealand, chips are often referred to as hot chips to distinguish them from potato chips, although the type of chip is often implied through context. Thomas Jefferson had potatoes served. in the French Manor at a White House dinner in 1802. The expression French Fried Potatoes first occurred in print in English in the 1856 work, Cookree for Mades of All Work, by Eliza Warren, French Fried Potatoes. Cut new potatoes in thin slices, put them in boiling fat and a little salt.
Starting point is 00:10:24 fry both sides of a light golden brown color. Drain. This account referred to thin, shallow-fried slices of potato. It is not clear where or when the now-familiar deep-fried batons or fingers of potato were first prepared. In the early 20th century, the term French-fried was being used in the sense of deep-fried for foods, like onion rings or chicken. The term was in use in the United States as early as 1880. An 1890 item in good housekeeping specifically references kitchen economy in France.
Starting point is 00:11:13 The perfection of French fries is due chiefly to the fact that plenty of fat is used. One legend about the name French fries claims that when the American expeditionary forces arrived in Belgium during World War I, they assumed that chips were a french dish because french was spoken in the belgian army but the name was used long before that in english even in the u s army and the popularity of the term did not increase for decades after nineteen seventeen the oldest documents where a fried potato is mentioned are from chile in sixteen twenty nine in the city of nascimento extracted from happy captivity, written in 1673 by Chilean Francisco Nunez de Pineda, where he narrates his experiences as a captive war soldier in 1629, at the hands of the Mapuche warriors.
Starting point is 00:12:24 In the text he mentioned eating Papas Ritas fried potatoes in 1629, and Mapuche women sent fried and stewed potatoes to the chiefs. the exact shape is unclear likely wide slices or cubes fried in lamb or guana cotello which was customary however the cane shape originates from europe french fries in their current form may have been invented in spain the first european country in which the potato appeared from the new world colonies professor paul ilgum's curator of the freed-musis in Bruges Belgium, believes that St. Teresa of Avila of Spain cook the first French fries, and refers also to the tradition of frying in Mediterranean cuisine as evidence. The Belgian food historian Pierre LaClerc has traced the history of the French fry and asserts that it is clear that fries are of French origin. It became an emblematic Parisian dish in the
Starting point is 00:13:42 the 19th century. Frederick Krieger, a Bavarian musician, learned to cook fries at a roaster on Rue Montmartre in Paris in 1842, and took the recipe to Belgium in 1844, where he created his business, treats, and sold Paris-style fried potatoes. The modern style of fries born in Paris around 1855 is different from the domestic fried potato that existed in the 18th century. From the Belgian standpoint, the popularity of the term French fries is explained as French gastronomic hegemony into which the cuisine of Belgium was assimilated, because of a lack of understanding coupled with a shared language and geographic proximity of the countries. The Belgian journalist Joe Gerard claimed that a 1781 family manuscript
Starting point is 00:14:48 recounts that potatoes were deep-fried prior to 1680 in the Muse Valley as a substitute for frying fish when the rivers were frozen. Gerard never produced the manuscript that supports this claim and the historical value of this story is open to question. In any case, it is unrelated to the later history of the French fry, as the potato did not arrive in the region until around 1735. Furthermore, given 18th century economic conditions, it is absolutely unthinkable that a peasant could have dedicated large quantities of fat for cooking potatoes. At most, they were sauteed in a pan. In France and other French-speaking countries, fried potatoes are formerly palms deer-fried,
Starting point is 00:15:50 but more commonly palms fried, fried apples, patats freed, or simply freets. The words egulids, needle-eds, or alamed matchsticks, are used when the French fries are very small and thin, One enduring origin story holds that French fries were invented by street vendors on the Pondouf Bridge in Paris in 1789, just before the outbreak of the French Revolution. However, a reference exists in France from 1775 to a few pieces of fried potato and to fried potatoes. Eating potatoes for sustenance was promoted in France by, Antoine, Augustine, Pomeritier, but he did not mention fried potatoes in particular. A note in a manuscript in U.S. President Thomas Jefferson's hand,
Starting point is 00:16:58 circa 1801 to 1809, mentions potatoes deep-fried while raw in small slices. The recipe almost certainly comes from his French chef, Honoré Julian. The thick-cut fries are called Poms Pornet. new for simply palms frit, about 10 millimeters. Thinner variants are palms al-a-met, matchstick potatoes, about 7 millimeters, and palms pale potato straws, 4 millimeters. Palm's gufret are waffle fries.

Often served with ketchup or mayonnaise, they are popular as a side dish in restaurants, or as a street food snack purchased at an imbistand snack stand. Since the 1950s,

Chips are more thickly cut than French fries, and they can be cooked once or multiple times at different temperatures. From 1813 on, recipes for deep-fried cut potatoes occur in. popular cookbooks. By the late 1850s, at least one cookbook refers to French-fried potatoes. The first commercially available chips in the UK were sold by Mrs. Granite-Duce in one of the West Riding towns in 1854. A blue plaque in Oldham marks the origin of the fish and chip

Subsequently, in 1967, Ray Crock of McDonald's, contracted the Simplot Company to supply them with frozen fries, replacing fresh-cut potatoes. In 2004, 29% of the United States potato crops were used to make frozen fries, 90% consumed by the food services sector, and 10% by retail.
