Helix pomatia, commonly known as the Roman snail, Burgundy snail, or edible snail, is a large, air-breathing land snail in the family Helicidae. Native to Europe, it is found throughout temperate regions from the British Isles to the Balkan Peninsula, preferring moist, deciduous forests, hedgerows, and limestone-rich grasslands where the calcium content in the soil allows for the construction of its robust, calcified shell. The genus name Helix is derived from the Greek word for "spiral," while the species epithet pomatia comes from the Greek pomatos, meaning "lid" or "operculum," a reference to the calcified epiphragm it secretes to seal its shell during winter hibernation. Historically, this species has been one of the most culturally significant gastropods in Western civilization, used as a food source since the Roman Empire and famously cultivated in monasteries during the Middle Ages.

The snail is a hermaphroditic mollusk, possessing both male and female reproductive organs, and is characterized by a large, globular, brownish-yellow shell that typically grows to a diameter of 3 to 5 centimeters. Its body is composed of a soft, muscular foot used for locomotion and a visceral mass protected within the shell. Helix pomatia is particularly well-adapted to surviving harsh, dry, or cold conditions; it enters a state of deep dormancy (estivation or hibernation) by retracting into its shell and creating a thick, hardened mucus-and-calcium seal. It is a nocturnal herbivore, feeding on a wide variety of green vegetation, including dandelion leaves, nettles, and tree foliage, which gives its flesh a distinct, clean, and earthy flavor.

Helix pomatia is the definitive ingredient in the classic French delicacy escargots de Bourgogne. Because the snail's diet consists of forest plants, its meat is firm, savory, and has a mild, mushroom-like umami character. Culinary preparation typically involves a thorough cleansing process—often followed by a period of fasting—before the snails are blanched, removed from their shells, and simmered in a court-bouillon (a flavorful broth of wine, herbs, and aromatics). The most iconic serving method features the snails returned to their cleaned shells and topped with a generous amount of garlic, parsley, and shallot-infused butter, then oven-roasted until bubbling.

Nutritionally, Helix pomatia is an exceptional source of lean, high-quality animal protein, making it a valued functional food in many traditional diets. It is remarkably low in fat and calories, while being dense in essential minerals, particularly iron, magnesium, and selenium. The meat also contains significant levels of Vitamin B12 and essential fatty acids. Beyond its nutritional profile, the mucus secreted by the snail—often referred to as snail slime or mucin—has been used in traditional medicine for centuries to treat respiratory conditions, such as bronchitis, due to its soothing, demulcent properties. In modern times, these extracts are highly sought after in the cosmetic and pharmaceutical industries for their skin-regenerating and wound-healing potential.
