Snails are considered edible in many areas such as the Mediterranean region, Africa, or Southeast Asia, while in other cultures, snails are seen as a taboo food. In American English, edible land snails are also called escargot, taken from the French word for 'snail,' and the production of snails for consumption is called snail farming or heliciculture. Snails as a food date back to ancient times, with numerous cultures worldwide having traditions and practices that attest to their consumption.
The snails are collected after the rains and are put to "purge" (fasting). In the past, the consumption of snails had a marked seasonality, from April to June. However, thanks to snail breeding techniques, today they are available all year round. Heliciculture occurs mainly in Spain, France, and Italy, which are also the countries with the greatest culinary tradition of the snail. Although throughout history the snail has had little value in the kitchen because it is considered "poverty food", in recent times it can be classified as a delicacy thanks to the appreciation given to it by haute cuisine chefs.
Etymology of escargot
Escargot, , comes from the French word for snail. One of the first recorded uses of the French word escargot, meaning dates from 1892. The French word (1549) derives from escaragol (Provençal) and thence escargol (Old French), and is ultimately – via Vulgar Latin coculium and Classical Latin conchylium – from the Ancient Greek konchylion (κογχύλιον), which meant "edible shellfish, oyster". The Online Etymological Dictionary writes, "The form of the word in Provençal and French seem to have been influenced by words related to the scarab."
History
Researchers have not been able to pinpoint when humans began consuming snails, although archaeological discoveries point to earlier stages than the invention of hunting. A lot of broken snail shells have been found in the Franchthi Cave, in the Greek Argolis, from the year 10,700 BCE. In Historia de gastronomía (2004), Fernández-Armesto points out the possible reasons: snails are easy to handle, and their cultivation "seems like a natural extension of harvesting." It is difficult to go beyond the limits of a developmentalist and progressive model of the history of food, according to which it is unthinkable that no food was cultivated in such early times, but snail farming is so simple, requires so little technical effort and is conceptually so close to harvesting methods, that it seems doctrinaire to the point of stubbornness to exclude such a possibility. – Felipe Fernandez-Armesto.Many sites in the Zagros Mountains of Iraq and the Kermanshah region of western Iran are from the late Pleistocene and include snail shells that have been interpreted as food debris. Specifically, these species were mainly Helix salomonica or Levantina spiriplana. The deposits with snails from the ancient Capsian culture (present-day Tunisia) are of notable importance, as well as those found in the Cantabrian Mountains, the Pyrenees and the northern Adriatic (present-day Croatia and Slovenia), in addition to many other remains of snails throughout the Mediterranean Basin. The most convincing evidence for prehistoric land snail consumption is found in the Maghreb, beginning in the Iberomaurusian (20 000 BP) and continuing through the Capsian to at least 6 000 BP. Outside the Mediterranean region, the occurrence of land snails as food debris is less common. According to , archaeological remains of land snails have been found in the Caribbean, Peru, Texas and other parts of North America, East Africa, Sudan, Nigeria, and the Philippines. Also, archaeological remains of freshwater snails have been found in Yunnan.
In ancient China, in The Book of Rites, a Confucian text, there is a mention of a snail sauce.
