Bacalao, a culinary staple in many cultures, particularly in Portugal, Spain, Italy, and the Caribbean, is more than just a dish; it’s a tradition, a flavor of home, and a testament to preservation. But what exactly is bacalao made of? The answer is deceptively simple, yet the journey from ocean to plate involves a fascinating process of curing and cultural significance.
The Humble Beginnings: Cod, the Star Ingredient
At its heart, bacalao is made from cod. Specifically, it’s salt cod, meaning cod that has been preserved through salting and drying. The type of cod used is usually Atlantic cod ( Gadus morhua ), a fish known for its firm, white flesh and relatively low fat content, making it ideal for this preservation method.
While other white fish can be salted and dried, and sometimes sold under similar names in different regions, true bacalao, according to traditional and legal definitions in many European countries, must be made from cod. The flavor, texture, and cooking characteristics are all intrinsically tied to this particular fish.
Why Cod? The Perfect Fish for Preservation
Cod possesses several characteristics that make it exceptionally well-suited for salting and drying:
-
Low Fat Content: The low fat content of cod is crucial. Fat can become rancid during the preservation process, spoiling the fish. Cod’s lean nature allows it to dry properly and last for extended periods.
-
Firm Flesh: Cod’s firm flesh holds up well during the salting and drying process, preventing it from becoming mushy or falling apart. It also contributes to the characteristic texture of bacalao after rehydration.
-
Size and Availability: Historically, cod was abundant in the North Atlantic, making it a readily available and affordable source of protein for communities in Europe and beyond.
The Art of Preservation: Salting and Drying
The process of transforming fresh cod into bacalao is a time-honored tradition that relies on the power of salt to inhibit bacterial growth and draw out moisture. This process essentially renders the fish shelf-stable for months, even years, without refrigeration.
The Salting Process: A Multi-Stage Transformation
The salting process typically involves these key steps:
-
Cleaning and Gutting: The fresh cod is first cleaned, gutted, and often split open or filleted.
-
Salting: The fish is then heavily salted, typically using coarse sea salt. The salt is rubbed into every surface of the fish, ensuring thorough coverage.
-
Stacking: The salted cod is stacked in layers, often with more salt sprinkled between each layer. This allows the salt to draw out moisture from the fish through osmosis.
-
Curing: The stacked fish is left to cure for a period of weeks or even months. During this time, the salt penetrates the flesh, inhibiting bacterial growth and firming the texture.
The Drying Process: Removing Residual Moisture
After the salting process, the fish is typically dried to further reduce its moisture content and prevent spoilage.
-
Air Drying: Traditionally, bacalao was air-dried outdoors, often on racks or wooden structures, in cold, dry climates. The wind and sun would slowly remove the remaining moisture from the fish.
-
Controlled Drying: Modern methods may involve controlled drying environments with regulated temperature and humidity to ensure consistent results and prevent contamination.
The final product is a hard, dry, and heavily salted piece of cod that can be stored for extended periods without refrigeration.
From Salted Cod to Culinary Delight: Rehydration is Key
Bacalao, in its preserved state, is inedible. Before it can be cooked and enjoyed, it must undergo a crucial rehydration process. This process not only removes the excess salt but also reintroduces moisture to the fish, restoring its texture and making it palatable.
The Desalting Process: Patience and Fresh Water
The desalting process typically involves soaking the bacalao in cold water for 24 to 72 hours, or even longer, depending on the thickness of the fish and the level of saltiness desired. The water should be changed frequently, typically every 6-8 hours, to effectively draw out the salt.
Some cooks also recommend gently scrubbing the surface of the fish during the desalting process to help remove any remaining salt crystals.
Testing for Saltiness: The Taste Test
The best way to determine if the bacalao has been sufficiently desalted is to taste a small piece. It should be only slightly salty, not overwhelmingly so. If it’s still too salty, continue soaking it in fresh water for a longer period, changing the water frequently.
Bacalao Around the World: Variations and Cultural Significance
Bacalao is not just a single dish; it’s a family of dishes, each with its own unique flavors and cultural significance. From the creamy bacalhau com natas in Portugal to the flavorful bacalao a la vizcaína in Spain, the possibilities are endless.
Portugal: The Land of a Thousand Bacalao Dishes
Portugal is perhaps the country most closely associated with bacalao. It’s said that there are more recipes for bacalao in Portugal than there are days in the year. Bacalhau à Brás, Bacalhau com Natas, and Bacalhau à Gomes de Sá are just a few of the many popular variations. Bacalao is a staple of Portuguese cuisine, often served during holidays and special occasions.

What exactly is bacalao and what fish is used to make it?
Bacalao, also known as bacalhau in Portuguese and bacalao in Spanish, is dried and salted cod. It’s a culinary staple in many cultures, particularly in Portugal, Spain, Norway, and Italy. The process of drying and salting preserves the fish, allowing it to be stored for long periods without refrigeration.
Typically, Atlantic cod (Gadus morhua) is used to create bacalao. This specific species is preferred due to its firm, white flesh and low fat content, which lends itself well to the drying and salting process. While other white fish can sometimes be used, true bacalao always originates from cod.
Is bacalao the same thing as stockfish (stoccafisso)?
While both bacalao and stockfish involve preserving cod, they are distinct products with different preparation methods. Bacalao is dried and salted, a process that draws moisture out of the fish while simultaneously preserving it with salt. The salting is a critical element of bacalao production.
Stockfish, on the other hand, is dried without the use of salt. It’s typically air-dried in cold climates for several months, relying on the natural environment for preservation. This results in a product that is significantly harder and requires a more extensive rehydration process than bacalao.
What makes the salting process so important for bacalao?
The salting process is crucial because it inhibits the growth of bacteria and microorganisms that cause spoilage. Salt draws out moisture from the fish, creating an environment where these organisms cannot thrive. This allows the cod to be preserved for extended periods without refrigeration.
Furthermore, the salting process significantly alters the texture and flavor of the fish. It firms the flesh, creating a characteristic chewy texture. It also infuses the cod with a distinct salty flavor that is integral to many bacalao dishes. The desalting process, therefore, is key to achieving the desired balance of flavor and texture.
How do you properly desalt bacalao before cooking?
The desalting process is essential for removing excess salt from the bacalao and rehydrating the fish. Begin by rinsing the bacalao under cold running water to remove any surface salt. Then, submerge the fish in a bowl or container of cold water, ensuring it is fully covered.
Change the water every 6-8 hours for a period of 24-72 hours, depending on the thickness of the fish and your personal preference for saltiness. Taste a small piece of the bacalao after each water change to monitor the salt level. Once it reaches your desired level of saltiness, it is ready to be cooked.
Can you eat bacalao without desalting it first?
Consuming bacalao without desalting it first is strongly discouraged. The salt content in the dried and salted cod is extremely high and would be unpalatable, not to mention potentially harmful due to the excessive sodium intake. The drying and salting process is specifically intended to preserve the fish, not to prepare it for immediate consumption.
Proper desalting is a critical step in preparing bacalao for any dish. Failing to desalt the fish will result in an overly salty and unpleasant eating experience. It also prevents the fish from properly absorbing flavors during the cooking process.
Where does bacalao come from and how has it been produced historically?
Historically, the best bacalao came from cod caught in the North Atlantic, particularly around Norway, Iceland, and Newfoundland. These regions provided the ideal conditions for both fishing and the drying/salting process, which required cold temperatures and a consistent breeze. These regions still remain prominent exporters of quality bacalao.
The production of bacalao has been a traditional practice for centuries, dating back to the Viking era. The drying and salting method allowed people to preserve fish for long journeys and harsh winters. Over time, the trade of bacalao played a significant role in the economies of several European countries, particularly Portugal and Spain.
Are there different grades or qualities of bacalao?
Yes, bacalao is available in different grades or qualities, which are usually determined by factors such as the size and thickness of the fish, the drying and salting process, and the overall appearance and texture. Some bacalao is made from thicker fillets, which command a higher price due to their superior meatiness.
The quality is also affected by how carefully the fish is processed. For instance, some producers use more precise methods to ensure even salting and drying, resulting in a more consistent and flavorful product. The best quality bacalao is typically thick, white, and free from blemishes or imperfections.
