Bacalhau, a word that rolls off the tongue with a hint of mystery and a promise of deliciousness, is a cornerstone of Portuguese cuisine. But what exactly is bacalhau in English? The answer is simpler than you might think: bacalhau translates directly to “cod.” However, this isn’t just any cod; it’s specifically dried and salted cod. This preservation method has transformed the simple codfish into a culinary icon with a rich history and a multitude of uses.
The Essence of Bacalhau: Beyond Simple Cod
Understanding bacalhau goes beyond simply knowing its English translation. The process of drying and salting the cod is what truly defines it and gives it its unique flavor, texture, and historical significance.
The Preservation Process: From Sea to Plate
The transformation of fresh cod into bacalhau is a time-honored tradition. The process typically involves the following steps:
- Catching the Cod: Traditionally, the cod used for bacalhau comes from the cold, nutrient-rich waters of the North Atlantic, primarily around Norway, Iceland, and Canada. The quality of the cod is crucial, with larger, meatier fish being preferred.
- Cleaning and Splitting: Once caught, the cod is cleaned, gutted, and split open, usually along the backbone. This prepares the fish for the salting process.
- Salting: This is the critical step that preserves the cod and gives it its characteristic flavor. The fish is layered with coarse salt, which draws out moisture and inhibits bacterial growth. The salting process can take several weeks or even months, depending on the size of the fish and the desired level of preservation.
- Drying: After salting, the cod is dried, either naturally in the open air or in controlled drying rooms. This further reduces the moisture content, ensuring long-term preservation.
The entire process results in a product that can be stored for extended periods without refrigeration, making it a valuable food source throughout history.
The Taste and Texture: A Culinary Profile
Bacalhau has a distinctive flavor profile that is both salty and slightly sweet. The drying and salting process intensifies the natural flavors of the cod, creating a unique umami taste. The texture is firm and flaky, but it requires rehydration before cooking. This rehydration process not only softens the fish but also removes excess salt, allowing the subtle flavors to shine through.
A History Steeped in Tradition
Bacalhau’s story is intertwined with the history of exploration, trade, and culinary innovation. Its origins can be traced back centuries, with evidence suggesting that Vikings were among the first to dry cod for preservation.
From Viking Voyages to Global Trade
The ability to preserve cod through drying and salting was a game-changer for seafaring nations. It allowed sailors to embark on long voyages without the risk of their food spoiling. Bacalhau became a staple food for explorers, traders, and fishermen, fueling the age of discovery.
Portugal, in particular, embraced bacalhau and integrated it into its culinary heritage. The Portuguese developed sophisticated salting and drying techniques and established extensive trade routes to import cod from the North Atlantic. Over time, bacalhau became deeply ingrained in Portuguese culture, with countless recipes and traditions associated with it.
Bacalhau in Portuguese Culture: A National Treasure
In Portugal, bacalhau is more than just a food; it’s a symbol of national identity. It’s said that there are over 365 ways to prepare bacalhau, one for each day of the year. From simple, home-style dishes to elaborate culinary creations, bacalhau features prominently in Portuguese cuisine. It’s a staple at family gatherings, festive celebrations, and religious occasions.
Cooking with Bacalhau: A Culinary Adventure
Preparing bacalhau requires some patience and understanding, but the results are well worth the effort. The first step is always rehydration, which typically involves soaking the fish in cold water for 24-48 hours, changing the water several times to remove excess salt.
The Art of Rehydration: Preparing for Culinary Greatness
The rehydration process is crucial for achieving the desired texture and flavor. The soaking time will depend on the thickness of the fish and the level of saltiness. It’s important to taste the fish periodically to determine when it’s adequately rehydrated. Once rehydrated, the bacalhau is ready to be cooked in a variety of ways.

Beyond Portugal: Bacalhau’s Global Influence
While bacalhau is most closely associated with Portugal, it’s also enjoyed in other parts of the world, particularly in countries with strong Portuguese cultural ties, such as Brazil and Angola. In these countries, bacalhau is prepared in a variety of ways, often incorporating local ingredients and flavors.
Furthermore, similar salted cod preparations are found in other cultures. Italy has “baccalà,” often prepared in a stew or fried. Caribbean islands use salt cod in dishes like “saltfish and ackee” in Jamaica. Each region adapts the basic preservation technique to suit their local tastes and ingredients.
Nutritional Value: A Healthy Choice
Bacalhau is not only delicious but also a nutritious food source. It’s a good source of protein, omega-3 fatty acids, and essential minerals.
Packed with Protein and Omega-3s
Bacalhau is a lean source of protein, making it an excellent choice for those looking to increase their protein intake. It’s also rich in omega-3 fatty acids, which are beneficial for heart health and brain function. These healthy fats contribute to overall well-being and can help reduce the risk of chronic diseases.
Rich in Essential Minerals
In addition to protein and omega-3s, bacalhau is also a good source of essential minerals, such as potassium, phosphorus, and calcium. These minerals play important roles in maintaining bone health, nerve function, and muscle function.
Buying and Storing Bacalhau: Tips for Success
When buying bacalhau, look for thick, firm fillets that are free of blemishes. The fish should have a pleasant aroma, not a strong, fishy smell. It’s best to buy bacalhau from a reputable source that specializes in seafood.
Selecting Quality Bacalhau
The quality of bacalhau varies, and choosing wisely can significantly impact the final dish. Look for the following:
- Thickness: Thicker fillets indicate a better quality fish and will yield more meat after rehydration.
- Color: The color should be a creamy white or slightly yellowish. Avoid fillets that are overly yellow or discolored.
- Smell: A fresh, clean smell is essential. Avoid any bacalhau that has a strong, ammonia-like odor.
- Texture: The fillet should be firm to the touch.
Proper Storage Techniques
Unrehydrated bacalhau can be stored in a cool, dry place for several months. Once rehydrated, it should be stored in the refrigerator and used within a few days. It’s important to keep rehydrated bacalhau covered in water to prevent it from drying out.
