Snails as food facts for kids
Snails are considered edible in certain areas such as the Mediterranean region, Africa, or Southeast Asia, while in other cultures it is considered as 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 food date back to ancient times, with numerous cultures around the world 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, French pronunciation: [ɛskaʁɡo] , 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 an exact time when humans began consuming snails, although archaeological discoveries point to earlier stages even 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". Unlike hunting large game, no guns or dogs are needed, and one's safety is not in jeopardy. Unlike other livestock, snails are easy to feed and can be raised in large numbers:
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 sp. 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, in East Africa, Sudan, Nigeria and in the Philippines. Also, archaeological remains of freshwater snails have been found in Yunnan.
Ancient Rome
The Romans considered escargots an elite food, as noted in the writings of Pliny the Elder. The Roman breeder Quintus Fulvius Lippinus is considered the "father" of heliciculture, or at least, the first written reference to snail farms. Lippinus established his study center in the Tuscan city of Tarquinia for the feasibility of domesticating various animals, such as dormouse and wild boar, among many others. However, he was best known for his enormous snails, of which he had several species brought from Illyria to Africa. With a fatty diet that he devised to fatten them, he obtained large quantities of snails, which he then marketed in Rome. His snails set a trend among the Roman upper class and the practice became popular. Lippinus was an innovator who managed a large company that marketed his snails beyond the Mare Nostrum. In De re coquinaria, one of the most complete Roman cookbooks, four recipes based on snails are mentioned. Shells of the edible species Cernuella virgata and Otala lactea were been recovered from the Roman-era city Volubilis, in present-day Morocco. They are a harbinger of the escargot found in modern souks of the country.
Modern Age
Pope Pius V, who was an avid eater of snails, decided that they had to be considered as fish, in order to continue eating them during Lent, exclaiming: Estote pisces in aeternum! ('you will be fish forever!'). In Spain, the custom continued to have continuity as can be seen in the gastronomic literature of that time. In the Libro del arte de cozina by Diego Granado –head chef of the Spanish royal household–, a section was dedicated to the snail, explaining its biological characteristics, how to clean it and various recipes on how to cook it, fry it, etc. Curiously, this book was published in 1614 in Lérida, a city in western Catalonia famous for its culinary tradition of the snail.
Species
Not all land snails are edible, since many are too small–not worthwhile to prepare and cook–and the palatability of the flesh varies among the species.

- Helix salomonica
From the genus Cepaea:
- Cepaea nemoralis, grove snail, known as rayado ('striped' snail) in Spain

From the genus Otala:
- Otala punctata, known as cabrilla in Spain, are bigger
- Otala lactea, Spanish snail
From the genus Pomacea:
- Pomacea canaliculata, apple snail, although native to South America, it is widely consumed in Asia, where it is considered a highly invasive species.
- Pomacea urceus, in Colombia and Venezuela, where it originates from, it is known as guarura
Others:
- Buccinum undatum, common whelk
- Cantareus apertus (formerly Helix aperta), garden snail
- Cornu aspersum (formerly Helix aspersa), common or garden snail, known as petit-gris in France
- Elona quimperiana, known as escargot de Quimper in France and caracol moteado in the north of Spain

Snail meat has several benefits compared to other meats, highlighting its low calorie and fat content. It is a source of protein (between 10 and 19%). Nutritional information can vary depending on the species of snail and also depending on who performs the nutritional analysis. Even so, it can be said that snails are rich in inorganic nutrients: on the one hand, 82% water. On the other, minerals such as magnesium and iron (mainly, but also calcium, phosphorus, potassium and sodium), in addition to a high percentage of niacin (vitamin B3), since for every 100 g of snail meat, up to a 55% of the DRI (in women) and 41% DRI (in men). Consumption of snails is a good source of selenium; Of the recommended daily amount of selenium required, the snail provides up to 50% (in women) and 30% (in men).
Due to its high iron content, the intake of snails is recommended for people suffering from iron-deficiency anemia. Its low fat content is beneficial because it provides the body with omega-3 fatty acids. In general, regular consumption of snails is beneficial for the treatment of depression, to strengthen the nervous and immune systems, prevent heart disease and regulate the thyroid gland.
Culinary use
Cleaning
Before using it in the kitchen, the snails must be previously cleaned to remove impurities. The cleaning process (called purgado in Spanish) consists of leaving them alive for several days without eating, or only eating flour. The flour method is a homemade resource to clean the digestive tract of the animal. Formerly in Spain, the snails were hung from mesh bags from which they could not escape. The snail chef (Morell i Bitrià 1999) recommends not giving them anything to eat for at least eight days (although ideally ten or twelve), and then washing them well. Snails that die during the purging process should be disposed of.
Preparation
The slime should be removed with as many washes of water as possible, with a colander under running water or in a saucepan. Again they are washed, but this time with salt water. The salt also helps cut through the slime. After being cleaned and washed several times, they are transferred to a pot with cold water and salt, and when they come out of their shell, the heat is raised to the maximum and they are cooked for approximately a quarter of an hour. After this, they are served in the chosen stew, sauce, or recipe. This intermediate action is popularly known as engañar ("cheating") the snail in Spain, since when they notice a certain heat they come out of their shell, and, once outside, the flame is raised so that they die at that moment.
Consumption
In bars where snails are offered as a tapa, it is common for it to be served with toothpicks, as this is the typical rustic utensil for eating snails. The ration for a common person ranges between 25 and 30 snails. In haute cuisine-style catering, snails are consumed by grasping the shell with a pince à escargot and extracting the snail with a fork called fourchette à escargot.
On a culinary level, they can be cooked in many ways: stews, baked, a la gormanta, a la brutesque. In the cuisine of Lleida, it is an ingredient in many traditional dishes, in many cases mixing it with other meats: snails with pig's feet, with rabbit, with chicken, with lobsters and prawns, etc.
By region
African Guinea
In Cameroon, Ghana, Nigeria and other countries in the area, they are used to eating the African variants of snail, which are larger. Typical of Equatorial Guinea is a giant sea snail called bilolá (Persististrombus latus), which is eaten stewed or sautéed, which in Cape Verde is known as búzio cabra, and it is grilled on skewers.
Mediterranean Basin
There is a tradition of consuming snails in Andorra, Spain, France, Italy and Portugal on the European side and Algeria, Morocco and Tunisia on the African side. Cornu aspersum is the most widespread species in the Mediterranean basin, the Iberian Peninsula and the French Atlantic coast.
In French cuisine, snails are typically purged, killed, shelled, and cooked (usually with garlic butter, chicken stock or wine), and then placed back into the shells with the butter and sauce for serving. Additional ingredients, such as garlic, thyme, parsley, and pine nuts, may be added. Special tongs for holding the shell and forks for extracting the meat are typically provided. Escargot are served on indented metal trays with places for six or 12 snails.
In Cretan cuisine, the snails are first boiled in white wine with bay leaves, celery, and onion and then coated with flour and fried with rosemary and vinegar.
In Maltese cuisine, snails (Maltese: bebbux) of the petit gris variety are simmered in red wine or ale with mint, basil and marjoram. The snails are cooked, and served in their shells.
In Moroccan cuisine, snails, also called Ghlal, are a popular street food. They are cooked in a jar filled with hot water, special spices, and herbs. After cooking, Moroccan snails are served in small bowls with their broth and consumed hot. Moroccan snails are mostly enjoyed during winter as they are believed to be beneficial for health, especially when dealing with the common cold or rheumatism.
A city known for its snail culture is the town of Lérida, in the north-Spanish region of Catalonia, where the L'Aplec del Caragol festival has been held since 1980, receiving some 300,000 visitors during a weekend in May.
Southeast Asia
Snails are consumed in Cambodia, the Philippines, Indonesia, Laos, Malaysia, Thailand and Vietnam. In Indonesia, snails from the rice fields are fried on satay (skewers), a dish known as sate kakul , or alternatively grilled, Tondano 's sate kolombi.
In the west of the island of Java, the snails from the rice fields are called tutut and are eaten with different sauces (curry, etc. ).
Other regions
- The Terai region in Nepal
- Northeast India (states of Manipur, Tripura and Nagaland). In Nagaland, the snails are prepared with axone and pork meat, especially the fats. Locally it is called 'hamok'. In Manipur, they are called 'tharoi'.
- North India (states of Uttar Pradesh and Bihar). In Bihar especially in Mithila region, they are called 'doka', at other places in Bihar and eastern Uttar Pradesh they are called 'ainthi'. They are boiled and the meat is extracted to cook a curry typically eaten with rice.
- A growing demand in South America, in particular, Argentina, Chile, Peru and Uruguay.
