Garum


Garum was a fermented fish sauce used as a condiment in the cuisines of Phoenicia, ancient Greece, Rome, Carthage and later Byzantium. Liquamen was a similar preparation, and at times they were synonymous. Although garum enjoyed its greatest popularity in the Western Mediterranean and the Roman world, it was earlier used by the Greeks.
Like the modern fermented soy product soy sauce, fermented garum is a rich source of umami flavoring due to the presence of glutamates. It was used along with murri in medieval Byzantine and Arab cuisine to give a savory flavor to dishes. Murri may well derive from garum.

Manufacture and export

and Isidore of Seville derive the Latin word garum from the Greek γαρός, a food named by Aristophanes, Sophocles, and Aeschylus. Garos may have been a type of fish, or a fish sauce similar to garum. Pliny stated that garum was made from fish intestines, with salt, creating a liquor, the garum, and the fish paste named allec or allex. A concentrated garum evaporated down to a thick paste with salt crystals was called muria; it would have been used to salt and flavor foods.
Garum was produced in various grades consumed by all social classes. After the liquid was ladled off of the top of the mixture, the remains of the fish, called allec, was used by the poorest classes to flavour their staple porridge or farinata. The finished product—the nobile garum of Martial's epigram—was apparently mild and subtle in flavor. The best garum fetched extraordinarily high prices, and salt could be substituted for it in a simpler dish. Garum appears in many recipes featured in the Roman cookbook Apicius. For example, Apicius gives a recipe for lamb stew, calling for the meat to be cooked with onion and coriander, pepper, lovage, cumin, liquamen, oil, and wine, then thickened with flour.
In the first century AD, liquamen was a sauce distinct from garum, as indicated throughout the Corpus Inscriptionum Latinarum IV. By the fifth century or earlier, however, liquamen had come to refer to garum. The available evidence suggests that the sauce was typically made by crushing the innards of pelagic fishes, particularly anchovies, but also sprats, sardines, mackerel, or tuna, and then fermenting them in brine. In most surviving tituli picti inscribed on amphorae, where the fish ingredient is shown, the fish is mackerel. Under the best conditions, the fermentation process took about 48 hours.
from Pompeii
The manufacture and export of garum was an element of the prosperity of coastal Greek emporia from the Ligurian coast of Gaul to the coast of Hispania Baetica, and perhaps an impetus for Roman penetration of these coastal regions. Although it was a staple of the Roman Empire's cuisine, few production sites were known to exist in the Eastern Mediterranean until a small 1st-century factory was discovered near Ashkelon in 2019.
Pliny the Elder spoke of a type of garum that Roman Jews may have used, as normal garum would not have been considered kosher.
In the ruins of Pompeii, jars were found containing kosher garum, suggesting an equal popularity among Jews there. Each port had its own traditional recipe, but by the time of Augustus, Romans considered the best to be garum from Cartagena and Gades in Baetica.
This product was called garum sociorum, "garum of the allies". The ruins of a garum factory remain at the Baetian site of Baelo Claudia and Carteia. Other sites are a large garum factory at Gades and at Málaga under the Picasso museum.
Garum was a major export product from Hispania to Rome, and gained the towns a certain amount of prestige. The garum of Lusitania was also highly prized in Rome, and was shipped directly from the harbour of Lacobriga. A former Roman garum factory can be visited in the Baixa area of central Lisbon. Fossae Marianae in southern Gaul, located on the southern tip of present-day France, served as a distribution hub for Western Europe, including Gaul, Germania, and Roman Britain.
Umbricius Scaurus' production of garum was key to the economy of Pompeii. The factories where garum was produced in Pompeii have not been uncovered, perhaps indicating that they lay outside the walls of the city. The production of garum created such unpleasant smells that factories were generally relegated to the outskirts of cities. In 2008, archaeologists used the residue from garum found in containers in Pompeii to confirm the August date of the eruption of Mount Vesuvius. The garum had been made entirely of bogues, fish that congregate in the summer months.

Cuisine

When mixed with wine, vinegar, black pepper, or oil, garum enhances the flavor of a wide variety of dishes, including boiled veal and steamed mussels, even pear-and-honey soufflé. Diluted with water it was distributed to Roman legions. Pliny remarked in his Natural History that it could be diluted to the colour of honey wine and drunk.

Social aspects

Garum had a social dimension that might be compared to that of garlic in some modern Western societies, or to the adoption of fish sauce in Vietnamese cuisine. Seneca, holding the old-fashioned line against the expensive craze, cautioned against it, even though his family was from Baetian Corduba:
A surviving fragment of Plato Comicus speaks of "putrid garum". Martial congratulates a friend on keeping up amorous advances to a girl who had indulged in six helpings of it.
The biological anthropologist Piers Mitchell suggests that garum may have helped spread fish tapeworms across Europe.

As medicine

Garum was also employed as a medicine. It was thought to be one of the best cures for many ailments, including dog bites, dysentery, and ulcers, and to ease chronic diarrhea and treat constipation. Garum was even used as an ingredient in cosmetics and for removal of unwanted hair and freckles.

Legacy

Garum remains of interest to food historians and chefs, and has been reintroduced into modern food preparation. In Southeast Asia, fish sauce is a distinctive element of that region's cuisine, used similarly as garum was in Rome. In Cádiz, Spain, in 2017, one chef used its flavors for a fish salad recipe, after Spanish archaeologists found evidence of garum in amphoras recovered in the ruins of Pompeii, dating to 79 AD.
Garum is believed to be the ancestor of the fermented anchovy sauce colatura di alici, still produced in Campania, Italy.
Worcestershire sauce is a savory sauce based upon fermented anchovies and other ingredients. Ketchup, originally a savory fish sauce that contained neither sugar nor tomatoes, shared its origins, culinary functions and popularity with garum.
