Ice cream (derived from earlier iced cream or cream ice) is a frozen food, typically eaten as a snack or dessert, usually made from dairy products, such as milk and cream, and often combined with fruits or other ingredients and flavours. It is typically sweetened with sucrose, corn syrup, cane sugar, beet sugar, and/or other sweeteners. Typically, flavourings and colourings are added in addition to stabilizers. The mixture is stirred to incorporate air spaces and cooled below the freezing point of water to prevent detectable ice crystals from forming. The result is a smooth, semi-solid foam that is solid at very low temperatures (<35 °F / 2 °C). It becomes more malleable as its temperature increases.
The meaning of the phrase "ice cream" varies from one country to another. Phrases such as "frozen custard", "frozen yogurt", "sorbet", "gelato" and others are used to distinguish different varieties and styles. In some countries, such as the United States, the phrase "ice cream" applies only to a specific variety, and most governments regulate the commercial use of the various terms according to the relative quantities of the main ingredients. Products that do not meet the criteria to be called ice cream are labelled "frozen dairy dessert" instead. In other countries, such as Italy and Argentina, one word is used for all variants. Analogues made from dairy alternatives, such as goat's or sheep's milk, or milk substitutes, are available for those who are lactose intolerant, allergic to dairy protein, or vegan. The most popular flavours of ice cream in North America (based on consumer surveys) are vanilla and chocolate.
Arabs used milk as a major ingredient in the production of ice cream and sweetened it with sugar rather than fruit juices. It was flavoured with rosewater, dried fruits and nuts. In the Persian Empire, people would pour grape-juice concentrate over snow, in a bowl, and eat this as a treat. This was done primarily when the weather was hot, using snow saved in the cool-keeping underground chambers known as "yakhchal", or taken from snowfall that remained at the top of mountains by the summer capital Ecbatana. In 400 BC, the Persians went further and invented a special chilled food, made of rose water and vermicelli, which was served to royalty during summers. The ice was mixed with saffron, fruits, and various other flavours.
The Roman Emperor Nero (37–68 AD) had ice brought from the mountains and combined it with fruit toppings to create chilled delicacies.
When Italian duchess Catherine de' Medici married the Duke of Orléans (Henry II of France) in 1533, she is said to have brought with her to France some Italian chefs who had recipes for flavoured ices or sorbets. One hundred years later, Charles I of England was, it was reported, so impressed by the "frozen snow" that he offered his own ice cream maker a lifetime pension in return for keeping the formula secret, so that ice cream could be a royal prerogative. There is no historical evidence to support these legends, which first appeared during the 19th century.
The first recipe in French for flavoured ices appears in 1674, in Nicholas Lemery’s Recueil de curiositéz rares et nouvelles de plus admirables effets de la nature. Recipes for sorbetti saw publication in the 1694 edition of Antonio Latini's Lo Scalco alla Moderna (The Modern Steward). Recipes for flavoured ices begin to appear in François Massialot's Nouvelle Instruction pour les Confitures, les Liqueurs, et les Fruits, starting with the 1692 edition. Massialot's recipes result in a coarse, pebbly texture. Latini claims that the results of his recipes should have the fine consistency of sugar and snow.
Ice cream recipes first appeared in 18th-century England. The recipe for ice cream was published in Mrs. Mary Eales's Receipts in London in 1718.
To ice cream.
Take Tin Ice-Pots, fill them with any Sort of Cream you like, either plain or sweeten’d, or Fruit in it; shut your Pots very close; to six Pots you must allow eighteen or twenty Pound of Ice, breaking the Ice very small; there will be some great Pieces, which lay at the Bottom and Top: You must have a Pail, and lay some Straw at the Bottom; then lay in your Ice, and put in amongst it a Pound of Bay-Salt; set in your Pots of Cream, and 93 lay Ice and Salt between every Pot, that they may not touch; but the Ice must lie round them on every Side; lay a good deal of Ice on the Top, cover the Pail with Straw, set it in a Cellar where no Sun or Light comes, it will be froze in four Hours, but it may stand longer; then take it out just as you use it; hold it in your Hand and it will slip out. When you wou’d freeze any Sort of Fruit, either Cherries, Rasberries, Currants, or Strawberries, fill your Tin-Pots with the Fruit, but as hollow as you can; put to them Lemmonade, made with Spring-Water and Lemmon-Juice sweeten’d; put enough in the Pots to make the Fruit hang together, and put them in Ice as you do Cream.
An early reference to ice cream given by the Oxford English Dictionary is from 1744, reprinted in a magazine in 1877. 1744 in Pennsylvania Mag. Hist. & Biogr. (1877) I. 126 Among the rarities..was some fine ice cream, which, with the strawberries and milk, eat most deliciously.
The 1751 edition of The Art of Cookery made Plain and Easy by Hannah Glasse features a recipe for ice cream. OED gives her recipe: H. GLASSE Art of Cookery (ed. 4) 333 (heading) To make Ice Cream..set it [sc. the cream] into the larger Bason. Fill it with Ice, and a Handful of Salt. The year 1768 saw the publication of L'Art de Bien Faire les Glaces d'Office by M. Emy, a cookbook devoted entirely to recipes for flavoured ices and ice cream.
Ice cream was introduced to the United States by Quaker colonists who brought their ice cream recipes with them. Confectioners sold ice cream at their shops in New York and other cities during the colonial era. Ben Franklin, George Washington, and Thomas Jefferson were known to have regularly eaten and served ice cream. First Lady Dolley Madison is also closely associated with the early history of ice cream in the United States. One respected history of ice cream states that, as the wife of U.S. President James Madison, she served ice cream at her husband's Inaugural Ball in 1813.
Small-scale handcranked ice cream freezer were invented in England by Agnes Marshall and in America by Nancy Johnson in the 1840s.
Expansion in popularity
In the Mediterranean, ice cream appears to have been accessible to ordinary people by the mid-eighteenth century. Ice cream became popular and inexpensive in England in the mid-nineteenth century, when Swiss emigre Carlo Gatti set up the first stand outside Charing Cross station in 1851. He sold scoops in shells for one penny. Prior to this, ice cream was an expensive treat confined to those with access to an ice house. Gatti built an 'ice well' to store ice that he cut from Regent's Canal under a contract with the Regent's Canal Company. By 1860, he expanded the business and began importing ice on a large scale from Norway.
Agnes Marshall, regarded as the 'queen of ices' in England did much to popularize ice cream recipes and make its consumption into a fashionable middle-class pursuit. She wrote four books: Ices Plain and Fancy: The Book of Ices (1885), Mrs. A.B. Marshall's Book of Cookery (1888), Mrs. A.B. Marshall's Larger Cookery Book of Extra Recipes (1891) and Fancy Ices (1894) and gave public lectures on cooking. She even suggested using liquid nitrogen to make ice cream.
Ice cream soda was invented in the 1870s, adding to ice cream's popularity. The invention of this cold treat is attributed to American Robert Green in 1874, although there is no conclusive evidence to prove his claim. The ice cream sundae originated in the late 19th century. Several men claimed to have created the first sundae, but there is no conclusive evidence to support any of their stories. Some sources say that the sundae was invented to circumvent blue laws, which forbade serving sodas on Sunday. Towns claiming to be the birthplace of the sundae include Buffalo, Two Rivers, Ithaca, and Evanston. Both the ice cream cone and banana split became popular in the early 20th century.
The first mention of the cone being used as an edible receptacle for the ice cream is in Mrs. A.B. Marshall's Book of Cookery of 1888. Her recipe for "Cornet with Cream" said that "the cornets were made with almonds and baked in the oven, not pressed between irons". The ice cream cone was popularized in the USA at the 1904 World's Fair in St. Louis, MO.
The history of ice cream in the 20th century is one of great change and increases in availability and popularity. In the United States in the early 20th century, the ice cream soda was a popular treat at the soda shop, the soda fountain, and the ice cream parlour. During American Prohibition, the soda fountain to some extent replaced the outlawed alcohol establishments such as bars and saloons.
Ice cream became popular throughout the world in the second half of the 20th century after cheap refrigeration became common. There was an explosion of ice cream stores and of flavours and types. Vendors often competed on the basis of variety. Howard Johnson's restaurants advertised "a world of 28 flavors". Baskin-Robbins made its 31 flavours ("one for every day of the month") the cornerstone of its marketing strategy. The company now boasts that it has developed over 1000 varieties.
One important development in the 20th century was the introduction of soft ice cream, which has more air mixed in thereby reducing costs. It made possible the soft ice cream machine in which a cone is filled beneath a spigot on order. In the United States, Dairy Queen, Carvel, and Tastee-Freez pioneered in establishing chains of soft-serve ice cream outlets.
Technological innovations such as these have introduced various food additives into ice cream, the notable one being the stabilizing agent gluten, to which some people have an intolerance. Recent awareness of this issue has prompted a number of manufacturers to start producing gluten-free ice cream.
The 1980s saw thicker ice creams being sold as "premium" and "super-premium" varieties under brands such as Ben & Jerry's, Chocolate Shoppe Ice Cream Company and Häagen-Dazs.
Before the development of modern refrigeration, ice cream was a luxury reserved for special occasions. Making it was quite laborious; ice was cut from lakes and ponds during the winter and stored in holes in the ground, or in wood-frame or brick ice houses, insulated by straw. Many farmers and plantation owners, including U.S. Presidents George Washington and Thomas Jefferson, cut and stored ice in the winter for use in the summer. Frederic Tudor of Boston turned ice harvesting and shipping into a big business, cutting ice in New England and shipping it around the world.
Ice cream was made by hand in a large bowl placed inside a tub filled with ice and salt. This was called the pot-freezer method. French confectioners refined the pot-freezer method, making ice cream in a sorbetière (a covered pail with a handle attached to the lid). In the pot-freezer method, the temperature of the ingredients is reduced by the mixture of crushed ice and salt. The salt water is cooled by the ice, and the action of the salt on the ice causes it to (partially) melt, absorbing latent heat and bringing the mixture below the freezing point of pure water. The immersed container can also make better thermal contact with the salty water and ice mixture than it could with ice alone.
The hand-cranked churn, which also uses ice and salt for cooling, replaced the pot-freezer method. The exact origin of the hand-cranked freezer is unknown, but the first U.S. patent for one was #3254 issued to Nancy Johnson on 9 September 1843. The hand-cranked churn produced smoother ice cream than the pot freezer and did it quicker. Many inventors patented improvements on Johnson's design.
In Europe and early America, ice cream was made and sold by small businesses, mostly confectioners and caterers. Jacob Fussell of Baltimore, Maryland was the first to manufacture ice cream on a large scale. Fussell bought fresh dairy products from farmers in York County, Pennsylvania, and sold them in Baltimore. An unstable demand for his dairy products often left him with a surplus of cream, which he made into ice cream. He built his first ice cream factory in Seven Valleys, Pennsylvania, in 1851. Two years later, he moved his factory to Baltimore. Later, he opened factories in several other cities and taught the business to others, who operated their own plants. Mass production reduced the cost of ice cream and added to its popularity.
The development of industrial refrigeration by German engineer Carl von Linde during the 1870s eliminated the need to cut and store natural ice, and, when the continuous-process freezer was perfected in 1926, commercial mass production of ice cream and the birth of the modern ice cream industry was underway.
The most common method for producing ice cream at home is to use an ice cream maker, in modern times, in general, an electrical device that churns the ice cream mixture while cooled inside a household freezer, or using a solution of pre-frozen salt and water, which gradually melts while the ice cream freezes. Some more expensive models have an inbuilt freezing element. A newer method of making home-made ice cream is to add liquid nitrogen to the mixture while stirring it using a spoon or spatula for a few seconds; a similar technique, advocated by Heston Blumenthal as ideal for home cooks, is to add dry ice to the mixture while stirring for a few minutes. Some ice cream recipes call for making a custard, folding in whipped cream, and immediately freezing the mixture.
Ice cream can be mass-produced and thus is widely available in developed parts of the world. Ice cream can be purchased in large cartons (vats and squrounds) from supermarkets and grocery stores, in smaller quantities from ice cream shops, convenience stores, and milk bars, and in individual servings from small carts or vans at public events.
Some ice cream distributors sell ice cream products from travelling refrigerated vans or carts (commonly referred to in the US as "ice cream trucks"), sometimes equipped with speakers playing children's music. The driver of an ice cream van drives throughout neighbourhoods and stops every so often, usually every block. The ice cream van is usually playing a jingle called Ice Cream by Andre Nickatina. The seller on the ice cream van sells the ice cream through a large window; this window is also where the customer asks for ice cream and pays. Ice cream vans in the United Kingdom make a music box noise rather than actual music.
INGREDIENTS AND STANDARD QUALITY DEFINITIONS
In the USA, ice cream may have the following composition:
These compositions are percentage by weight. Since ice cream can contain as much as half air by volume, these numbers may be reduced by as much as half if cited by volume. In terms of dietary considerations, the percentages by weight are more relevant. Even the low-fat products have high caloric content: Ben and Jerry's No-Fat Vanilla Fudge contains 150 calories (630 kJ) per half-cup due to its high sugar content.
Ice cream cone
Reliable evidence proves that ice cream cones were served in the 19th century, and their popularity increased greatly during the St. Louis World's Fair in 1904. According to legend, at the World's Fair an ice cream seller had run out of the cardboard dishes used to put ice cream scoops in, so they could not sell any more produce. Next door to the ice cream booth was a Syrian waffle booth, unsuccessful due to intense heat; the waffle maker offered to make cones by rolling up his waffles and the new product sold well, and was widely copied by other vendors.
OTHER FROZEN DESSERTS
The following is a partial list of ice cream-like frozen desserts and snacks:
Using liquid nitrogen to freeze ice cream is an old idea and has been used for many years to harden ice cream. The use of liquid nitrogen in the primary freezing of ice cream, that is to effect the transition from the liquid to the frozen state without the use of a conventional ice cream freezer, has only recently started to see commercialization. Some commercial innovations have been documented in the National Cryogenic Society Magazine "Cold Facts". The most noted brands are Dippin' Dots, Blue Sky Creamery, Project Creamery, and Sub Zero Cryo Creamery. The preparation results in a column of white condensed water vapour cloud, reminiscent of popular depictions of witches' cauldrons. The ice cream, dangerous to eat while still "steaming", is allowed to rest until the liquid nitrogen is completely vaporised. Sometimes ice cream is frozen to the sides of the container, and must be allowed to thaw.
Making ice cream with liquid nitrogen has advantages over conventional freezing. Due to the rapid freezing, the crystal grains are smaller, giving the ice cream a creamier texture, and allowing one to get the same texture by using less milkfat. Such ice crystals will grow very quickly via the processes of recrystallization, thereby obviating the original benefits unless steps are taken to inhibit ice crystal growth.
For similar reasons, good results can also be achieved with the more readily available "dry ice" and authors such as Heston Blumenthal have published recipes to produce ice cream and sorbet using a simple blender.
