The term ice cream is sometimes used to mean frozen desserts and snacks in general although ice cream is usually reserved for frozen desserts and snacks made with a high percentage of milk fat.
Typical definitions for frozen desserts and snacks:
Many countries, e.g. the United States, regulate the use of these terms based on specific percent quantities of ingredients.
Ice creams come in a wide variety of flavours, often with additives such as chocolate flakes or chips, nuts, fruit, and small candies/sweets. Some of the most popular ice cream flavours in supermarkets are vanillaFor other uses, see vanilla (disambiguation). Vanilla is a flavoring, in its pure form known as vanillin, derived from orchids in the genus Vanilla''. The name came from the Spanish word "vainilla", diminutive form of "vaina" (meaning " sheath"), which is, chocolate, strawberryThe strawberry Fragaria is the fruit of a plant in the family Rosaceae (Rose Family). It is an accessory fruit; that is, the fleshy part is derived not from the ovaries (which are the seeds, actually achenes) but from the peg at the bottom of the hypanthi and NeapolitanNeapolitan is a kind of ice cream, or more precisely, of ice cream packaging: a third of the box (or tub, bar, etc. is strawberry, a third is chocolate, and a third is vanilla. There can be other combinations (eg. banana/vanilla/chocolate or caramel/vanil (a combination of the three).

Ice cream vans are often seen parked at public events, or near parks, beaches, or other in the UK Before the development of modern refrigeration by GermanThe Federal Republic of Germany ( German: Bundesrepublik Deutschland is one of the world's leading industrialized countries, located in the middle of the European Union. It is bordered to the north by the North Sea, Denmark and the Baltic Sea, to the east engineer Carl von Linde during the 1870s, ice cream was a luxury item reserved for very special occasions. Today, ice cream is enjoyed around the world on a daily basis thanks to commercial mass-production and the home freezer. Ice cream is often bought in large tubs from supermarkets/grocery stores, in smaller quantities from ice cream shops, convenience stores and milk bars, and in individual serves from small carts/vans at public events and places. There are even some ice cream manufacturers who sell ice cream products door-to-door from travelling refrigerated vans.
Modern commercial ice cream is made from a mixture of:
These ingredients make up the solid part of the ice cream, but only 50% of the final volume, the remainder being air incorporated during the whipping process. Generally, the cheaper the ice-cream, the cheaper the ingredients, and the more air is incorporated (since ice cream is sold by volume, it's economically advantageous for producers to reduce the density of the product). Artisan-produced ice creams, such as Berthillon's, often contain none to very little air.
There are several popular legends surrounding the discovery of ice cream. Marco Polo supposedly saw ice cream being made on his trip to China, bringing the recipe home to Italy with him on his return. From there, Catherine de Medici's Italian chefs are said to have carried the recipe to France when she went there in 1533 to marry the Duc d'Orléans. Charles I was supposedly 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, however, no historical evidence to support this legend, which first appeared during the 19th century and was probably created by imaginative ice cream vendors. Ice cream most likely did originate in China, but it is unknown how and when the idea made its way into the Western world.
The making of ice cream was originally an extremely laborious process. Ice was cut commercially from lakes and ponds during the winter and stored in large heaps in holes in the ground, insulated by straw. Ice cream was made by hand in a large bowl surrounded by packed ice. The hand-cranked churn was invented in 1846, making production simpler, and the world's first commercial ice cream factory opened in Baltimore, Maryland in 1851. A big factor in making the production easier, obviating the need for cutting and storing natural ice, was the development of modern refrigeration during the 1870s (see above). The continuous process freezer was perfected in 1926, allowing commercial mass-production of ice cream and the birth of the modern ice cream industry.
The most common method for producing ice-cream at home is to use an ice-cream machine, generally some electrical device that churns the ice cream while refrigerated inside a household freezer.
A less common method is by mixing liquid nitrogen into the preparation, with vigorous stirring. The preparation is spectacular, since it results in a column of white condensed vapor, reminiscent of movie depictions of witches' cauldrons. The result, due to the extreme rapid cooling of the mixture, is a very smooth ice cream containing only small ice crystals. For obvious reasons, such a method is generally only used by physicists or other scientists with easy access to liquid nitrogen, in particular by graduate students. Important warning: As long as the liquid nitrogen has completely vaporized, the remaining nitrogen bubbles are perfectly harmless, since nitrogen is anyway the major component of air; however, the nitrogen used in laboratories may have been contaminated by other chemicals, possibly harmful. Furthermore, care has to be taken not to leave chunks of very cold ice inside the mix. Wikipedia does not advocate the use of this method of preparation; see Disclaimers .
