Bacalao. The word rolls off the tongue with a certain exotic flair. But what exactly is bacalao? For many, the answer isn’t immediately obvious. It’s not a fish species like cod or salmon, nor is it a complex culinary preparation involving numerous ingredients. The truth is simpler, yet steeped in history and tradition. Bacalao, in English, refers to salt cod, specifically cod that has been preserved by drying after being salted.
The Essence of Salt Cod: More Than Just Preserved Fish
At its heart, bacalao is a method of preserving cod, a plentiful fish species found in the cold waters of the North Atlantic. Salting and drying dramatically extend the shelf life of the fish, allowing it to be transported and consumed in regions where fresh cod was unavailable. This preservation method transformed cod from a perishable commodity into a staple food.
But bacalao is far more than simply preserved fish. The salting and drying process imparts a unique texture and flavor that differentiates it from fresh cod. It’s a culinary transformation, creating a product with its own distinct character. This character is then further shaped by the myriad of ways it’s prepared in different cuisines around the world.
The Salting and Drying Process: A Time-Honored Tradition
The process of making bacalao is deceptively simple, yet requires skill and attention to detail. The cod is first gutted and split open, then heavily salted. This salt draws out moisture from the fish, inhibiting bacterial growth and preventing spoilage. The salted cod is then laid out to dry, often in the open air, further reducing its moisture content.
The drying process can take several weeks or even months, depending on the climate and the desired level of dryness. Throughout this time, the fish is carefully monitored to ensure that it dries evenly and does not spoil. The result is a firm, leathery product that can be stored for extended periods without refrigeration.
Why Cod? The Ideal Fish for Preservation
Cod is particularly well-suited for salting and drying due to its lean flesh. The low fat content helps the salt to penetrate the fish more effectively, drawing out moisture and preventing rancidity. The firm texture of cod also holds up well to the salting and drying process, preventing it from becoming mushy or falling apart. Other types of fish can be preserved this way, but cod is the most popular and widely recognized.
Bacalao Around the World: A Culinary Chameleon
Bacalao is a cornerstone of many cuisines, particularly in Southern Europe, Latin America, and the Caribbean. Its versatility allows it to be incorporated into a wide range of dishes, from hearty stews to delicate appetizers. Each region has its own unique way of preparing and serving bacalao, reflecting local ingredients and culinary traditions.
Portugal: The Land of a Thousand Bacalao Dishes
Portugal is perhaps the country most closely associated with bacalao. It’s often said that there are more recipes for bacalao in Portugal than there are days in the year. From the simple “bacalhau cozido” (boiled salt cod with potatoes and vegetables) to the elaborate “bacalhau à Brás” (shredded salt cod with scrambled eggs and potatoes), bacalao is a ubiquitous presence on Portuguese tables.
The Portuguese have elevated bacalao to an art form, celebrating its versatility and unique flavor. It’s a symbol of national identity and a testament to the resourcefulness of Portuguese sailors who relied on salt cod for sustenance during long voyages.
Spain: From Tapas to Main Courses
In Spain, bacalao, known as “bacalao,” is another highly cherished ingredient, especially during Lent and Christmas. It appears in tapas, such as “bacalao al pil pil” (salt cod cooked in garlic-infused olive oil), as well as main courses like “bacalao a la vizcaína” (salt cod in a tomato and pepper sauce).
Different regions of Spain have their own distinct bacalao recipes, showcasing the diversity of Spanish cuisine. From the Basque Country to Catalonia, bacalao is a staple ingredient that adds a unique depth of flavor to countless dishes.
Italy: A Southern Staple
While not as ubiquitous as in Portugal and Spain, bacalao (often referred to as “baccalà” or “stoccafisso,” depending on whether it’s salted and dried or just dried) plays a significant role in Italian cuisine, particularly in the southern regions. It’s often featured in hearty stews and fried dishes, especially during the Christmas season. “Baccalà alla lucana” (salt cod cooked with tomatoes, peppers, and onions) is a popular dish from the Basilicata region.
Latin America and the Caribbean: A Taste of Home
Bacalao made its way to Latin America and the Caribbean through European colonization, and it has since become an integral part of the local culinary landscape. In countries like Brazil, Mexico, and Jamaica, bacalao is used in a variety of dishes, often combined with local ingredients and spices to create unique and flavorful culinary creations. “Bacalaítos” (salt cod fritters) are a popular snack in Puerto Rico, while “bacalao con papas” (salt cod with potatoes) is a comforting dish enjoyed in many Latin American countries.
Preparing Bacalao: A Step-by-Step Guide to Desalting
Before bacalao can be used in any recipe, it must be desalted. The salting process, while essential for preservation, makes the fish far too salty to eat directly. Desalting is a crucial step that restores the fish to a palatable state.
The Desalting Process: Patience is Key
The desalting process typically involves soaking the bacalao in cold water for 24 to 72 hours, depending on the thickness of the fish and the level of saltiness. The water should be changed several times a day to effectively remove the salt.
Here’s a basic guide to desalting bacalao:
- Rinse the bacalao under cold running water to remove any excess salt crystals.
- Place the bacalao in a large bowl or container filled with cold water.
- Refrigerate the bowl to keep the water cold.
- Change the water every 6-8 hours.
- Test the bacalao after 24 hours by taking a small piece and tasting it. If it is still too salty, continue soaking it, changing the water regularly.
- The desalting process is complete when the bacalao is only slightly salty to the taste.
Tips for Successful Desalting
- Use cold water: Cold water helps to prevent the fish from becoming mushy during the desalting process.
- Change the water frequently: This is crucial for effectively removing the salt.
- Don’t over-desalt: It’s better to err on the side of slightly salty than to completely remove all the salt from the fish. A little bit of salt enhances the flavor.
- Refrigerate: Keep the bacalao refrigerated during the desalting process to prevent bacterial growth.
- Patience: Desalting takes time, so be patient and allow the fish to soak for the recommended amount of time.
After Desalting: Ready for Culinary Adventures
Once the bacalao has been desalted, it’s ready to be used in your favorite recipes. It can be boiled, baked, fried, grilled, or used in stews and salads. The possibilities are endless. The desalted bacalao should be stored in the refrigerator and used within a few days.
Bacalao: A Nutritious and Sustainable Choice
Beyond its culinary appeal, bacalao offers nutritional benefits and can be a sustainable seafood choice when sourced responsibly.
Nutritional Value: A Lean Protein Source
Bacalao is a lean source of protein, rich in essential amino acids. It’s also low in fat and calories, making it a healthy option for those watching their weight or cholesterol levels. Furthermore, it provides important vitamins and minerals, including vitamin D, vitamin B12, and selenium.
Sustainability: Choosing Responsibly Sourced Cod
Overfishing has been a concern for cod populations in the past. However, sustainable fishing practices are now in place in many regions. When purchasing bacalao, look for certifications such as the Marine Stewardship Council (MSC) label, which indicates that the fish has been harvested sustainably. Supporting responsible fisheries helps to ensure that cod populations remain healthy for future generations.

From the shores of Portugal to the tables of Latin America, bacalao has captivated palates and nourished communities for centuries. Understanding the process of salting and drying, the importance of desalting, and the versatility of this ingredient opens up a world of culinary possibilities. So, the next time you encounter the word “bacalao,” you’ll know that it represents not just salt cod, but also a delicious and enduring part of global culinary heritage. It is a testament to human ingenuity in food preservation and the power of simple ingredients to create extraordinary flavors.
What exactly is Bacalao?
Bacalao is the Portuguese and Spanish name for dried and salted cod. The process of salting and drying preserves the fish, preventing spoilage and making it shelf-stable for extended periods. This preservation method has been used for centuries, allowing communities to store and transport cod long before refrigeration.
While the name “Bacalao” specifically refers to cod that has been both dried and salted, it is important to note that simply drying cod or salting cod alone doesn’t constitute Bacalao. The combination of both processes is what gives it its unique texture, flavor, and extended shelf life. It is a staple ingredient in many cuisines, particularly those in Portugal, Spain, and Latin America.
How is Bacalao made?
The process of making Bacalao begins with fresh cod, typically Atlantic cod, which is gutted, cleaned, and filleted. The fillets are then heavily salted, often using a dry-salting method where the fish is packed in layers of salt. This process draws out moisture from the fish, inhibiting bacterial growth.
Following the salting, the cod is laid out to dry, traditionally in the open air, though modern methods may involve controlled drying environments. The drying process further reduces the moisture content, resulting in a firm, almost leathery texture. The final product, Bacalao, can be stored for years without refrigeration.
Why is Bacalao salted and dried?
Salting and drying are traditional methods of preserving food, particularly fish, that predate modern refrigeration. Salt draws moisture out of the fish, creating an environment that is inhospitable to bacteria and other microorganisms that cause spoilage. Drying further reduces moisture content, extending the shelf life significantly.
These preservation techniques were especially vital in regions where fresh fish was not readily available or where long voyages were required to transport food. Bacalao provided a reliable source of protein and nutrients for sailors, explorers, and communities living far from the coast. The concentrated flavor developed during the process also became highly valued.
What does Bacalao taste like?
Bacalao, in its raw, dried and salted state, is extremely salty and not palatable. However, once properly rehydrated, its flavor transforms into a rich and savory experience. The texture is firm and flaky, offering a satisfying bite.
The flavor profile of prepared Bacalao is complex and nuanced, often described as subtly sweet, slightly briny, and deeply umami. The saltiness, while initially intense, mellows out during the soaking process, leaving behind a pleasant background note that complements other ingredients. The final taste is heavily influenced by the preparation methods and accompanying flavors, ranging from simple garlic and olive oil to rich tomato-based stews.
How do you prepare Bacalao for cooking?
The key to preparing Bacalao lies in rehydrating it. Because of the heavy salting and drying, it needs to be soaked in cold water for at least 24 hours, and often longer, changing the water several times. This process removes excess salt and rehydrates the flesh, making it pliable and ready for cooking.
The soaking time depends on the thickness of the fillet and the level of saltiness desired. Some cooks recommend up to three days of soaking, with water changes every 6-8 hours. After soaking, the Bacalao is typically poached or simmered before being incorporated into various dishes. It’s crucial to taste the fish after soaking to ensure it’s not too salty.
What are some common dishes made with Bacalao?
Bacalao is a versatile ingredient used in a wide array of dishes, particularly in Portuguese and Spanish cuisine. In Portugal, it’s said there are over 365 ways to prepare Bacalao, with popular dishes including Bacalhau à Brás (shredded cod with scrambled eggs and fried potatoes), Bacalhau com Natas (cod with cream and potatoes), and Pasteis de Bacalhau (cod fritters).
In Spain, Bacalao is featured in dishes like Bacalao al Pil Pil (cod cooked in garlic-infused olive oil, creating a creamy emulsion), Bacalao a la Vizcaína (cod in a tomato and pepper sauce), and Croquetas de Bacalao (cod croquettes). Beyond Europe, Bacalao is also used in Latin American cuisine, often in stews, salads, and fritters.
Is Bacalao healthy?
Yes, Bacalao is generally considered a healthy food choice, especially after the excess salt is removed through soaking. It is a good source of lean protein, essential for building and repairing tissues. It is also relatively low in fat, particularly saturated fat.
Furthermore, Bacalao contains omega-3 fatty acids, which are beneficial for heart health and brain function. It also provides important vitamins and minerals, such as vitamin D, vitamin B12, and selenium. However, due to its high sodium content before soaking, individuals with sodium-sensitive conditions should consume it in moderation and ensure thorough soaking.
