Cod, a widely consumed fish enjoyed in various culinary traditions, often finds itself in a linguistic and culinary entanglement with “bacalao.” But are they truly the same? The short answer is both yes and no. While bacalao undeniably originates from cod, the transformation it undergoes significantly alters its character, making it distinct from the fresh or frozen cod you might find at your local supermarket. Let’s dive deep into the fascinating world of bacalao and cod to understand their relationship and appreciate their individual merits.
The Cod Foundation
Cod, belonging to the Gadus genus, is a family of fish cherished for its mild flavor, flaky texture, and versatility. Atlantic cod (Gadus morhua) is the most commonly used variety for both fresh consumption and bacalao production. Pacific cod (Gadus macrocephalus), while also suitable, is less frequently employed for bacalao due to subtle differences in texture and fat content.
Cod’s nutritional profile is impressive. It’s a lean protein source, rich in vitamins B12 and D, and minerals like iodine and phosphorus. Its low-fat content makes it a healthy choice for various diets.
Before we get into the specifics of how cod becomes bacalao, understanding the basics of the fish itself is crucial. Cod thrives in cold waters and has been a staple food source for centuries, particularly in coastal communities around the North Atlantic.
Bacalao: The Art of Preservation and Transformation
Bacalao isn’t just cod; it’s cod that has been preserved through salting and drying. This process, dating back centuries, was essential for preserving fish before refrigeration technology became widespread. The technique not only extended the shelf life of the cod but also dramatically altered its flavor and texture.
The Salting Process: A Deep Dive
The transformation from cod to bacalao begins with carefully selecting fresh cod. The fish is then gutted, cleaned, and filleted. Next, it’s heavily salted, a process that draws out moisture and inhibits bacterial growth.
The salting stage isn’t a simple application of salt. It’s a meticulously controlled procedure where the salt penetrates the fish tissue, changing its protein structure and inhibiting enzymatic activity that would lead to spoilage. This process can take several weeks, depending on the size of the fish and the desired final product.
The Drying Phase: Completing the Metamorphosis
Following the salting, the cod undergoes a drying phase, traditionally achieved by laying the salted fish out in the sun and wind. Nowadays, some producers utilize controlled drying chambers to ensure consistent results.
The drying process further reduces moisture content, creating a firm, almost leathery texture. This step is crucial for long-term preservation and for developing the characteristic flavor of bacalao. The degree of dryness also affects the final product; some bacalao is drier than others, depending on the intended use.
Why Salting and Drying? The Historical Significance
Salting and drying were essential for survival in many coastal communities, especially during long winters when fresh fish was scarce. Bacalao became a valuable commodity, traded and consumed throughout Europe and beyond.
The technique enabled sailors and explorers to carry a nutritious and durable food source on long voyages. Without the ability to preserve fish, many historical expeditions would have been impossible.
Bacalao vs. Cod: Key Differences
While bacalao starts as cod, the preservation process creates significant differences in several key aspects:
Flavor Profile
Fresh or frozen cod has a mild, slightly sweet flavor. Bacalao, on the other hand, boasts a much more intense, savory, and salty flavor. The salting process infuses the fish with a deep umami character that is absent in fresh cod.
The drying process further concentrates these flavors, leading to a more complex taste profile. Depending on the quality of the fish and the salting/drying method, bacalao can have subtle nuances that connoisseurs appreciate.
Texture
Fresh cod has a flaky, delicate texture. Bacalao, after salting and drying, becomes firm and dense. Rehydrating bacalao is essential to restore its tenderness. When properly prepared, bacalao has a unique, slightly chewy texture that is quite different from fresh cod.
The texture of bacalao also varies depending on the cut of the fish. Some parts are more fibrous, while others are more gelatinous.
Preparation and Usage
Fresh cod can be cooked in countless ways – baked, fried, steamed, poached, or grilled. Bacalao, however, requires a soaking process to remove excess salt before it can be cooked. This soaking can take anywhere from 24 to 72 hours, with frequent water changes.
Bacalao is a star ingredient in numerous traditional dishes around the world. From Portugal’s Bacalhau à Brás to Spain’s Bacalao al Pil Pil, the salted cod takes center stage in flavorful and satisfying meals.
Nutritional Value: Salt Content Considerations
While cod and bacalao share a similar nutritional foundation, the salt content of bacalao is significantly higher. This is a crucial consideration for individuals monitoring their sodium intake.
The soaking process helps reduce the salt content, but even after soaking, bacalao remains a relatively high-sodium food. Therefore, it’s essential to balance bacalao consumption with other low-sodium foods in your diet.
Global Culinary Traditions: Bacalao’s Starring Role
Bacalao’s impact on global cuisine is undeniable. It’s a beloved ingredient in countries across Europe, Latin America, and the Caribbean. Each region has developed its own unique recipes and culinary traditions centered around this preserved cod.

What exactly is bacalao and how does it differ from fresh cod?
Bacalao is not simply fresh cod; it refers specifically to cod that has been preserved through salting and drying. This preservation method, practiced for centuries, significantly extends the shelf life of the fish, making it a staple food source in regions where fresh fish was scarce or inaccessible. The process of salting and drying alters the texture and flavor profile of the cod, creating a distinct product from its fresh counterpart.
Fresh cod, on the other hand, is the cod fish in its natural, unprocessed state. It’s available raw at seafood markets or grocery stores and requires immediate cooking or freezing to prevent spoilage. While bacalao requires rehydration and often multiple rounds of desalting before cooking, fresh cod is ready to be cooked almost immediately. The flavor of fresh cod is milder and less intense compared to the salty, more concentrated flavor of bacalao.
Is bacalao always made from Atlantic cod, or can other types of cod be used?
While Atlantic cod ( Gadus morhua ) is the most commonly used species for bacalao, it’s not the only one. Other types of cod, such as Pacific cod ( Gadus macrocephalus ), can also be used to produce salted and dried cod, though the resulting product may differ slightly in flavor and texture. The specific type of cod used will often be indicated on the packaging, so it’s worth checking if you have a preference.
The quality and characteristics of bacalao are influenced not only by the species of cod used but also by the salting and drying process itself. Factors like the type of salt, the duration of the curing process, and the drying conditions all contribute to the final product. Therefore, while Atlantic cod is the traditional and often preferred choice, bacalao made from other cod species can still be a delicious and acceptable alternative.
How do you properly prepare bacalao before cooking?
Proper preparation of bacalao is crucial to remove the excess salt and rehydrate the fish, restoring its texture and making it palatable. The most common method involves soaking the bacalao in cold water for 24 to 72 hours, changing the water every 8 to 12 hours. The soaking time depends on the thickness of the fish and the degree of saltiness desired.
The desalting process is essential to ensure that the final dish is not overly salty. After soaking, taste a small piece of the bacalao to determine if it needs further desalting. Once sufficiently desalinated, the bacalao is ready to be used in various recipes. Remember to discard the soaking water, as it contains a high concentration of salt.
What are some popular dishes that feature bacalao?
