Snail caviar

Snail caviar (caviar d'escargots, sometimes referred to as escargot pearls) is a type of caviar that consists of fresh or processed eggs of land snails.

In their natural state, the eggs are colorless. After processing, the caviar may be cream-colored, pinkish-white, or white, with the eggs generally 3–4 mm in diameter. Some snail eggs may measure at 3–6 mm in diameter. Some commercial snail farms that produce escargot include the production of snail caviar as a part of their operations. In September 2014, the retail value of one brand of snail caviar was over €150 for a 50-gram jar.

The raw snail eggs have a slick shell that is delicate and breakable. They are sometimes pasteurized to preserve them. However, the pasteurization of snail eggs has been described as having a tarnishing effect upon their flavor. Some preserved versions are processed and jarred without the use of pasteurization, using brine as a preservative. Some producers use a flavored brine to add flavor to the product.

The flavor of snail caviar has been described in some instances as being reminiscent of "baked asparagus", and in other instances as being like "baked mushroom". It has also been described as having a "subtle" flavor with "woody notes", as having a "strong earthy" flavor, and as being crunchier than fish egg caviar. It may be served as other caviars are, with toast points, sour cream and champagne. It may also be served in soups, and in other ways.

Snail farming is referred to as heliciculture, and includes the process of farming or raising land snails specifically for human consumption. Some commercial snail farms collect and process snail caviar, which is then jarred and marketed to consumers. Sometimes the snails are raised and kept in temperature, lighting and climate controlled conditions to encourage maximal reproduction, which produces the eggs. Since snails are hermaphroditic (having both male and female sexual organs), all can produce eggs. Snails typically bury their eggs in soil after they are laid. One method of harvesting the eggs involves placing the snails in boxes that have soil and sand in them, whereupon the eggs are gathered. Snail egg output is meager when compared to fish roe production such as that from sturgeon. As a comparison, one snail typically lays approximately four grams of eggs annually, whereas one sturgeon may have up to 18 kilograms (40 lb) of eggs.
