Salt cod, also known as bacalao or saltfish, is a staple ingredient in many cuisines around the world, particularly in Mediterranean, Caribbean, and Latin American cooking. The process of soaking salt cod is crucial to rehydrate the fish and remove excess salt, making it palatable and ready for use in various recipes. In this article, we will delve into the world of salt cod and provide a comprehensive guide on how to soak it to perfection.
Understanding Salt Cod
Before we dive into the soaking process, it’s essential to understand what salt cod is and how it’s made. Salt cod is made from dried and salted codfish, typically from the Atlantic cod species. The fish is cleaned, gutted, and split open, then covered in a generous amount of salt to draw out moisture and preserve the flesh. The salt helps to prevent bacterial growth, allowing the fish to be stored for extended periods.
The Importance of Soaking Salt Cod
Soaking salt cod is a critical step in preparing the fish for cooking. The soaking process helps to:
- Rehydrate the fish: Salt cod is extremely dry and needs to be rehydrated to make it palatable.
- Remove excess salt: The soaking process helps to remove excess salt from the fish, making it less salty and more flavorful.
- Restore texture: Soaking helps to restore the fish’s natural texture, making it more tender and easier to cook.
How to Soak Salt Cod
Soaking salt cod is a relatively simple process that requires some planning and patience. Here’s a step-by-step guide on how to soak salt cod:
Step 1: Rinse the Salt Cod
Before soaking the salt cod, rinse it under cold running water to remove any loose salt or debris. This helps to prevent any excess salt from dissolving into the soaking liquid.
Step 2: Choose a Soaking Liquid
You can soak salt cod in various liquids, including:
- Cold water: This is the most common soaking liquid, and it’s recommended for most recipes.
- Milk or buttermilk: Soaking salt cod in milk or buttermilk helps to add moisture and tenderness to the fish.
- White wine or vinegar: Soaking salt cod in white wine or vinegar adds flavor and helps to balance the saltiness.
Step 3: Soak the Salt Cod
Place the rinsed salt cod in a large container or bowl, and cover it with the chosen soaking liquid. Make sure the fish is completely submerged in the liquid. Cover the container with plastic wrap or a lid, and refrigerate it at a temperature of 40°F (4°C) or below.
Soaking Times
The soaking time for salt cod varies depending on the thickness of the fish and the desired level of rehydration. Here are some general guidelines:
- Thin pieces of salt cod: 8-12 hours
- Thicker pieces of salt cod: 12-24 hours
- Extra-thick pieces of salt cod: 24-48 hours
Step 4: Change the Soaking Liquid
It’s essential to change the soaking liquid at least once during the soaking process to remove excess salt and prevent the growth of bacteria. After 8-12 hours, drain the soaking liquid and replace it with fresh liquid. Repeat this process until the desired soaking time is reached.
Step 5: Rinse and Pat Dry
Once the soaking process is complete, remove the salt cod from the liquid and rinse it under cold running water to remove any excess salt. Pat the fish dry with paper towels to remove excess moisture.
Tips and Variations
Here are some tips and variations to keep in mind when soaking salt cod:
- Use a weighted object: Place a weighted object, such as a plate or a can, on top of the salt cod to keep it submerged in the soaking liquid.
- Monitor the temperature: Make sure the soaking liquid is kept at a consistent refrigerator temperature to prevent bacterial growth.
- Add flavorings: You can add flavorings, such as garlic, onion, or herbs, to the soaking liquid to infuse the fish with extra flavor.
- Use a brine solution: You can soak salt cod in a brine solution (water, salt, and sugar) to add extra flavor and moisture.
Common Mistakes to Avoid
Here are some common mistakes to avoid when soaking salt cod:
- Over-soaking: Soaking salt cod for too long can make it too salty or mushy.
- Under-soaking: Soaking salt cod for too short a time can result in a fish that’s still too salty or dry.
- Not changing the soaking liquid: Failing to change the soaking liquid can lead to bacterial growth and off-flavors.

What is Salt Cod and Why Soak It?
Salt cod is a type of dried and salted fish that has been preserved through a process of salting and drying. It is a popular ingredient in many cuisines, particularly in Mediterranean and Latin American cooking. Soaking salt cod is necessary to rehydrate the fish and remove excess salt before cooking.
The soaking process helps to restore the fish’s natural texture and flavor, making it more palatable and easier to work with. Without soaking, the fish would be too salty and dry to eat. By soaking the salt cod, you can reconstitute it and use it in a variety of dishes, such as stews, soups, and salads.
How Long Does it Take to Soak Salt Cod?
The soaking time for salt cod can vary depending on the thickness of the fish and personal preference. Generally, it takes around 24 to 48 hours to soak salt cod. The fish should be soaked in cold water, changed several times during the process, to remove excess salt and rehydrate the flesh.
It’s essential to check the fish periodically during the soaking process to ensure it’s not becoming too soft or mushy. If you prefer a milder flavor, you can soak the fish for a shorter period, such as 12 hours. However, if you prefer a more intense flavor, you can soak it for a longer period, such as 72 hours.
What is the Best Way to Store Salt Cod?
Salt cod should be stored in a cool, dry place, away from direct sunlight and moisture. It’s best to keep it in an airtight container or plastic bag to prevent air from reaching the fish and causing it to spoil. You can also store salt cod in the refrigerator to keep it fresh for a longer period.
When storing salt cod, make sure to keep it away from strong-smelling foods, as the fish can absorb odors easily. It’s also essential to check the fish regularly for signs of spoilage, such as mold or a strong ammonia smell. If you notice any of these signs, it’s best to discard the fish immediately.
Can I Use Salt Cod in Any Recipe?
Salt cod can be used in a variety of recipes, but it’s not suitable for all dishes. Due to its strong flavor and firm texture, it’s best to use salt cod in recipes where it can be the main ingredient or where its flavor can be balanced by other ingredients. Salt cod is commonly used in stews, soups, salads, and pasta dishes.
However, salt cod may not be the best choice for recipes where delicate flavors are required, such as in sushi or sashimi. It’s also not recommended to use salt cod in recipes where it will be cooked for an extended period, as it can become dry and tough. It’s essential to choose recipes that complement the unique flavor and texture of salt cod.
How Do I Know if the Salt Cod is Fresh?
Fresh salt cod should have a firm texture and a mild, slightly sweet smell. It should not have any visible signs of mold or slime. When you touch the fish, it should feel dry and slightly springy. If the fish feels soft or mushy, it may be past its prime.
You can also check the packaging or labeling to ensure the salt cod is within its expiration date. If you’re purchasing salt cod from a fish market or store, ask the vendor about the origin and freshness of the fish. A reputable vendor should be able to provide you with information about the fish’s quality and freshness.
Can I Soak Salt Cod in Other Liquids Besides Water?
While water is the most common liquid used to soak salt cod, you can also use other liquids to add flavor to the fish. Some common alternatives include milk, white wine, or broth. Soaking the fish in these liquids can help to remove excess salt and add flavor to the fish.
However, it’s essential to note that using other liquids can affect the flavor and texture of the fish. For example, soaking the fish in milk can make it more tender and creamy, while soaking it in white wine can add a slightly acidic flavor. Experiment with different liquids to find the one that works best for your recipe.
Is Salt Cod a Healthy Food Option?
Salt cod can be a healthy food option if consumed in moderation. It is a good source of protein, omega-3 fatty acids, and various vitamins and minerals. However, it is also high in sodium due to the salting process. To make salt cod a healthier option, it’s essential to soak it properly to remove excess salt and cook it using low-sodium methods.
Additionally, salt cod can be high in mercury, a toxic substance that can harm human health. To minimize exposure to mercury, it’s recommended to consume salt cod in moderation and choose fish from reputable sources that have been tested for mercury levels. Pregnant women and young children should also limit their consumption of salt cod due to the potential health risks.
