Fried Arengada: history, tradition and the essence of Catalan cuisine

Arengada is one of the most traditional and symbolic preparations of Catalan gastronomy. It consists of a sardine preserved in brine and then pressed, which can be eaten grilled, roasted, or fried. Despite its simplicity, this product represents the essence of the old Catalan peasant cuisine, known for its resourcefulness, preservation techniques and respect for Mediterranean ingredients.

Origin of the name

The word “arengada” derives from the term herring. However, in Catalonia it is traditionally made with sardines rather than actual herring. Historically, larger sardines that were not considered ideal for fresh consumption were used for this preparation.

The traditional preservation method was simple but effective:

1. The sardines were cleaned as soon as they arrived at the port.
2. They were submerged in water with abundant salt.
3. Afterwards they were drained and placed in cylindrical containers.
4. Finally they were subjected to a pressing process that lasted about eight days.

During this time, weight was gradually added to the containers so the fish would release part of its oil. This process of curing and pressing is known as “arengar”, which ultimately gave the product its name: arengada.

A preservation technique with ancient roots

Preserving fish with salt is an ancient practice throughout the Mediterranean. As early as the Roman Empire, salting fish was a common method used to extend its shelf life and transport it across long distances.

Catalonia inherited and refined these techniques, particularly in coastal communities where sardine catches were abundant. For centuries, traditional fishmongers and cod shops displayed large wooden barrels filled with neatly arranged arengadas, a sight that has largely disappeared in modern urban markets.

A humble food with historical significance

For generations, arengada was considered a modest food associated with working-class and rural diets. Its strong flavor, nutritional value and low price made it a practical meal for farmers and laborers working long days in the countryside.

A curious historical anecdote links arengadas to the Spanish Civil War (1936–1939). In many Catalan farmhouses, two salted sardines were hung from a stick outside the window. This acted as a discreet signal warning that a pair of Civil Guard officers were nearby. Because of this, the fish earned the popular nickname “civiles” or “guardia civiles.”

Regions where the tradition survives

Today it is difficult to see the traditional barrels of arengadas in large cities such as Barcelona. However, the tradition still survives in several inland Catalan regions, particularly in:

• Pallars
• La Noguera
• Les Garrigues
• Montsià

In these areas, small markets and traditional food shops still preserve this product as part of the region’s culinary heritage.

Traditional Catalan dishes with arengada

Arengada has historically been used in several rural Catalan dishes, including:

Clotxa (Terres de l’Ebre)
A rustic peasant dish consisting of a hollowed loaf of country bread filled with salted sardine, roasted garlic, tomato, onion, olive oil and salt. It was commonly eaten by farmers while working in the fields.

Trinxat with arengada (Cerdanya)
A mountain dish made with mashed potatoes and cabbage sautéed with garlic and bacon, traditionally topped with a salted sardine that adds a distinctive salty contrast.
