Bacalao, that intensely flavored, salt-preserved cod, is a staple in cuisines across the globe, particularly in Portugal, Spain, Italy, and the Caribbean. But where did this enduring food tradition originate? The story of bacalao is a tale of resourcefulness, exploration, and the enduring power of preservation. It’s a journey that spans centuries and crosses vast oceans, connecting Vikings, Basque fishermen, and entire nations through a shared culinary heritage.
The Viking Connection: The Dawn of Dried Fish
Long before refrigeration, humans relied on preservation techniques to store food for leaner times. Drying and salting were among the most effective methods. While the precise origins of salted cod are debated, many historians point to the Vikings as pioneers in preserving fish through air-drying as early as the 9th century.
These Norse seafarers, venturing across the North Atlantic, discovered the abundance of cod in the waters off Norway and Iceland. They developed a process of hanging the fish to dry in the cold, windy air. This “stockfish,” unsalted and rock-hard, provided a crucial source of protein for their long voyages and harsh winters.
Although not the salted bacalao we know today, this dried cod laid the foundation for its development. It demonstrated the power of preservation in transforming a perishable resource into a stable, long-lasting food source. The Viking method of drying cod spread throughout Scandinavia and beyond, influencing preservation techniques in other parts of Europe.
The Basque Influence: Mastering the Art of Salting
While the Vikings dried their cod, the Basques, a seafaring people inhabiting the region between Spain and France, are widely credited with perfecting the art of salting cod, giving rise to the bacalao tradition that endures today.
The Basques were renowned fishermen and whalers. Around the 15th century, they began venturing further north, drawn by the rich cod fishing grounds off the coast of Newfoundland, Canada. This area, teeming with cod, became a critical resource for their burgeoning industry.
Recognizing the need for a preservation method suitable for long sea voyages back to Europe, the Basques adapted the Viking drying technique, incorporating salt as a primary preservative. They layered the cod with coarse sea salt, drawing out moisture and inhibiting bacterial growth. This process resulted in a product that could last for months, even years, without spoiling. This salted cod, known as bacalao (Spanish) or bacalhau (Portuguese), became a valuable trade commodity.
The Basque mastery of salting cod was a pivotal moment in the history of bacalao. It transformed a regional food source into a global culinary ingredient. Their expertise in fishing, preserving, and trading established bacalao as a vital part of the European economy.
The Secret Salting Techniques
The success of the Basque bacalao lay in their meticulous salting techniques. The process involved carefully cleaning and splitting the cod, then layering it with specific quantities of salt, ensuring thorough preservation. The curing process would take several weeks, with the fish being regularly turned and re-salted. This attention to detail resulted in a high-quality product that was both flavorful and long-lasting. Different levels of salting also allowed for variation based on transportation conditions and intended consumption time.
The Basque Monopoly on Cod
For centuries, the Basques held a virtual monopoly on the bacalao trade. Their seafaring skills, knowledge of cod fishing grounds, and expertise in salting techniques gave them a distinct advantage. They established trade routes that spanned Europe, supplying bacalao to countries throughout the continent. This dominance solidified bacalao’s place in European cuisine and cemented the Basques’ legacy as the pioneers of the industry.
The Portuguese Passion: Bacalhau as a National Dish
While the Basques perfected the preservation of bacalao, it was the Portuguese who truly embraced it and elevated it to a national culinary treasure. The Portuguese began consuming bacalao in earnest in the 16th century, and it quickly became a dietary staple, particularly during Lent and other religious holidays when meat consumption was restricted.
The Portuguese navigators, like their Basque counterparts, relied on bacalao as a crucial source of protein during their voyages of exploration. The long shelf life of bacalao made it an ideal food for extended periods at sea. As Portugal established its vast colonial empire, bacalao became an integral part of its culinary culture, spreading to its colonies in Africa, Asia, and South America.
The love for bacalao in Portugal transcends mere sustenance. It is deeply ingrained in the nation’s cultural identity. It is said that there are more than 365 ways to prepare bacalhau in Portugal, one for every day of the year. From simple grilled preparations to elaborate stews and casseroles, bacalao features prominently on menus throughout the country.
“Fiel Amigo” (Faithful Friend)
Bacalao is often referred to as “fiel amigo” (faithful friend) in Portugal, reflecting its enduring presence in the country’s culinary landscape. This affectionate nickname speaks to the deep connection the Portuguese have with this humble yet versatile ingredient. It is more than just food; it is a symbol of Portuguese heritage and tradition.
Bacalhau à Brás: A Culinary Icon

The salty saga continues, with each new recipe and each new generation of cooks adding their own chapter to the enduring story of bacalao.
What is Bacalao and what makes it unique?
Bacalao, often known as bacalhau in Portuguese or bacalao in Spanish, is dried and salted cod. This method of preservation allows the fish to be stored for long periods without refrigeration, making it a staple food in many cultures, particularly in regions with strong maritime traditions. The drying process concentrates the flavor, resulting in a distinct and intense taste that sets it apart from fresh cod.
The unique characteristics of Bacalao stem from both the type of fish used (primarily Atlantic cod, Gadus morhua) and the specific methods of drying and salting. The salt draws out moisture, preventing bacterial growth and altering the fish’s texture. After rehydration, Bacalao has a firm, flaky texture and a savory, slightly salty flavor, making it a versatile ingredient for a wide array of dishes.
Why was drying and salting cod such an important preservation technique?
Before modern refrigeration, drying and salting were vital methods for preserving food, especially fish. Cod, being a lean fish with low oil content, was particularly well-suited to this technique. Drying and salting significantly reduced the water activity in the fish, inhibiting the growth of bacteria, molds, and yeasts that cause spoilage. This allowed communities far from the sea to access a protein-rich food source.
The significance of this preservation method extends beyond simple food security. It enabled long sea voyages and exploration, as dried and salted cod could sustain crews for months at sea. It also facilitated trade routes, allowing cod to be transported and sold in inland markets. In essence, drying and salting cod revolutionized food preservation and supported economic growth.
Where did the practice of drying and salting cod originate?
While the exact origin is debated, evidence suggests that the practice of drying and salting cod predates recorded history, with possible roots in the pre-Roman Iberian Peninsula. Early methods likely involved sun-drying the fish, gradually incorporating salt to further extend its shelf life. Over time, the techniques were refined and adapted to different climates and cod varieties.
The widespread adoption of drying and salting cod is often attributed to the Vikings, who around 1000 AD, developed a highly efficient method of air-drying cod on wooden racks without salt. This “stockfish” was a crucial part of their diet during long voyages and harsh winters. However, the use of salt became more prominent as trade expanded, leading to the “bacalao” we know today, particularly driven by Basque fishermen.
How did the Basque people contribute to the Bacalao trade and tradition?
The Basque people, an ethnic group inhabiting the western Pyrenees straddling Spain and France, played a crucial role in the development and expansion of the Bacalao trade. They were skilled seafarers and fishermen, venturing far into the North Atlantic in search of cod, likely reaching Newfoundland centuries before Columbus. They possessed the knowledge and expertise to effectively catch, process, and preserve cod on a large scale.
Their superior shipbuilding and navigation skills, coupled with their knowledge of cod fishing grounds, allowed them to dominate the Bacalao trade for centuries. They established trade routes across Europe, distributing their dried and salted cod to diverse markets. Their influence is evident in the culinary traditions of many countries, particularly in Spain and Portugal, where Bacalao has become a central ingredient in countless dishes.
What role did Newfoundland play in the history of Bacalao?
Newfoundland, located off the eastern coast of Canada, became a pivotal location in the Bacalao story due to its abundant cod stocks. European fishermen, including the Basques, Portuguese, English, and French, flocked to Newfoundland’s Grand Banks, one of the world’s richest fishing grounds, to harvest cod. The island provided ideal conditions for drying cod due to its cool, dry climate and ample shoreline.
Newfoundland served as a central processing and trading hub for Bacalao. Fishermen would catch cod, process it on shore, and then either dry it in the open air or salt it for preservation. The dried and salted cod would then be shipped back to Europe, fueling the continent’s demand for this nutritious and preservable food source. This cod fishery shaped Newfoundland’s economy and culture for centuries.
How is Bacalao prepared before cooking?
Before cooking, Bacalao requires a rehydration process to remove the excess salt and restore its moisture content. This typically involves soaking the fish in cold water for 24 to 72 hours, depending on the thickness of the fillet and the level of saltiness. The water should be changed multiple times during the soaking period to effectively leach out the salt.
The rehydration process not only removes salt but also plumps up the fish, making it more tender and palatable. Some cooks prefer to lightly boil the Bacalao after soaking to further soften the texture and remove any remaining salt. Once rehydrated and desalted, Bacalao can be used in a wide variety of dishes, from stews and casseroles to salads and fritters.
How does Bacalao differ from stockfish?
While both Bacalao and stockfish are preserved cod, the key difference lies in the preservation method. Bacalao is salted and then dried, while stockfish is simply dried in the open air without any salting. This difference in preservation technique results in distinct flavor profiles and textures.
Stockfish has a much stronger and more concentrated fish flavor due to the absence of salt, and its texture is extremely firm and dense. Bacalao, on the other hand, has a milder, saltier flavor, and its texture is firmer than fresh cod but softer than stockfish. These differences influence their culinary applications, with stockfish often requiring more extensive soaking and cooking times than Bacalao.
