“They need little food, and require no one to feed them…the cook usually doesn’t know whether they are alive or dead when he is cooking them.”
~ Marcus Terentius Varro, De re agricultura (On Matters of Agriculture), 1st century BCE
If you’ve ever eaten land snails in the form of French escargots, rich with butter, parsley and garlic, I have upsetting news: depending on where you live, there’s a good chance those snails arrived at the restaurant dead, in a can.
There are a few reasons why. First, the importation of live land snails is highly regulated in many countries because the animals can become serious agricultural pests. As snails are hermaphrodites, just one escapee is enough for a population explosion. Another reason canned snails are commonly used in restaurants is that snail-farming is a daunting task, requiring a great deal of time, money, and space. Snails have a remarkable adaptation to prevent overpopulation: there are chemicals in their slime trails that inhibit reproduction in other snails. If one snail slimes across the trail of another, it becomes less likely to breed. The more snails sharing a tight space, the more likely they are to cross each other’s trails, meaning fewer baby snails and less profit for the aspiring heliciculturist (try saying that three times fast).
Despite the challenges of snail-farming, the Ancient Romans seem to have had it pretty well-figured out. The Roman snail-pen was called a cochlearium, the Latin word for snail being cochlea (a Greek loanword that can also mean “spiral”, hence the spiral cochlea in your inner ear). Cochlearia were a common sight on the grounds of Roman villas, alongside apiaria (beehives) and gliraria (dormouse hutches). The Roman scholar Varro, who lived in the 2nd and 1st centuries BCE, describes how to set up your own snail farm, including a pre-Industrial sprinkler system to keep the little molluscs hydrated:
“You must take a place fitted for snails, in the open, and enclose it entirely with water…The best place is one which the sun does not parch, and where the dew falls. If there is no such natural place…you should make an artificially dewy one. This can be done if you run a pipe and attach to it small teats, to squirt out the water in such a way that it will strike a stone and be scattered widely in a mist.”
Romans fed snails on milk, bran, and bay leaves. One disturbing recipe in the Roman cookbook Apicius (which has a whole chapter on snails) describes the force-feeding of snails for the table. The chef is instructed to remove the operculum, the flat, hard “door” that snails use to seal their shells, before placing the snails in a shallow layer of milk. Without the operculum, the snail can no longer withdraw into its shell, and its body will hang outside and grow unnaturally fat.
The Romans ate many species of snail. Archaeologists have uncovered the shells of Otala lactea (the milk or Spanish snail) in the Roman city of Volubilis in modern Morocco. Helix pomatia, the snail most commonly served as escargots, is still known as the “Roman snail” in the UK because it was introduced there from mainland Europe during the Roman period (43-410 CE). Varro names others whose species is difficult to guess; the “small white snails” of Reate in central Italy, medium snails from Africa, large ones from the Balkan province of Illyricum. The very largest snail, which Varro calls the solitanna, also came from Africa. Varro claims that a shell from one of these whoppers had a volume of 80 quadrantes; around 2.5 gallons. This is almost certainly a member of the Achatinidae family, several African species known for being the largest land snails in the world, but no snail recorded in modern times matches the size of Varro’s solitanna. Perhaps a comparison can be made to another historical mollusc: the oysters of New York City. For centuries, humans scoured the East and Hudson Rivers for the largest oysters they could find, so that they gradually dwindled in size from dinner plates to pennies before disappearing altogether.
The recipe below is adapted from Apicius 324 (Book VII, Chapter XVI: Snails). As Apicius often lacks serving suggestions, I followed the example of Pliny the Younger, pairing the snails with bread and lettuce.
-1 can of land snails (mine contained 24, which is about two servings. I bought it at Hong Kong Supermarket in Manhattan’s Chinatown.)
-2 tablespoons olive oil
-2 tablespoons fish sauce (Asian fish sauce is a close substitute for Roman liquamen and garum. Three Crabs is my favorite.)
-1 and 1/2 teaspoons ground black pepper
-2 teaspoons ground cumin
-crusty Italian or French bread, sliced (whole wheat is more authentically Roman)
Remove snails from the can, rinse in cold water, and pat dry.
Heat the olive oil in a pan over medium heat. Add the snails and stir for 2-3 minutes.
Add fish sauce, pepper, and cumin. Mix thoroughly and cook a little longer (total cooking time should be 7-10 minutes; too long and the snails will get rubbery).
Serve hot, with sliced bread and lettuce.
The snails are tender, very flavorful and salty, and the bread and lettuce balance them out nicely. I’ve eaten French, Vietnamese, and Korean-style snails and whelks, and this is the first time I’ve had them without garlic. I feel like garlic might have taken this recipe to the next level, but I’m pleased with it overall. Try it at your next Roman dinner party! IX out of X.
