How to Desalt Codfish for Cooking (Step-by-Step)

Salted codfish, also known as salt cod, saltfish, bacalao, or morue, is a beloved pantry staple throughout the Caribbean. But before it can be sautéed, fried, or folded into your favorite dish, it must be properly desalted.

Because salt cod is heavily preserved with salt, learning how to desalt codfish correctly ensures balanced flavor, tender texture, and authentic results in traditional Caribbean cooking.

Salted codfish is a pantry staple across the Caribbean, but cooking it properly starts long before it hits the skillet. Because it is heavily preserved with salt, learning how to desalt codfish correctly ensures balanced flavor, tender texture, and authentic results in traditional dishes.

If you skip this step or rush it, your final dish will be overwhelmingly salty and unpleasant. Let’s do it properly.

Why Is Salted Cod So Salty?

Salted cod is preserved using a heavy curing process. Before refrigeration, fish was packed in salt and dried to extend its shelf life for months.

This process:

• Draws out moisture
• Firms the flesh
• Intensifies flavor
• Makes long storage possible

However, before cooking, the excess salt must be removed, and the fish rehydrated. Proper soaking restores moisture and improves texture while reducing saltiness to a manageable level.

How to Desalt Codfish Properly

There are three reliable methods depending on your time and the thickness of the fish.

Method 1: Traditional Overnight Soak (Recommended)

This is the best method for balanced flavor and texture.

1. Rinse the salted cod under cold running water to remove surface salt.
2. Place the fish in a large bowl.
3. Cover completely with cold water.
4. Refrigerate for 8–24 hours.
5. Change the water 2–3 times during soaking.

This slow soak gently removes excess salt while preserving texture.

Best for:

• Fritters (accras)
• Saltfish and avocado
• Rice dishes
• Stews

Extended Soak (For Thick Pieces)

If the cod fillets are very thick or heavily salted:

• Soak for up to 48 hours.
• Change the water every 8 hours.
• Keep refrigerated at all times.

This ensures deeper desalting for large pieces.

Method 2: Boiling Method (Faster Option with Vinegar)

This method is ideal when you’re short on time. Adding vinegar helps freshen the fish and slightly neutralize strong saltiness.

Step-by-Step

1. Rinse the salted cod thoroughly under running water to remove surface salt.
2. Place the fish in a large pot and cover completely with fresh water.
3. Add 1 tablespoon of white vinegar to the water.
4. Bring to a boil over medium heat.
5. Once foam begins to rise (about 8–10 minutes), remove from heat and discard the water.
6. Rinse the fish gently.
7. Refill the pot with fresh water, add another 1 tablespoon of vinegar, and boil again for 10 minutes.
8. Drain and allow the fish to cool completely.
9. Remove skin and bones, rinse lightly, and pat dry before cooking.

Boiling softens the fish slightly more than the cold soaking method. If you want firmer texture (for salads or fritters), use the soaking method instead.

How to Know When It’s Ready

After soaking:

• The fish should feel softer and slightly plump.
• The salt smell should be milder.
• When tasted, it should be seasoned and not overly salty.

Always test a small flake before cooking your full dish.

Common Mistakes When Desalting Codfish

Avoid these common errors:

• Soaking at room temperature: always refrigerate during long soaks. Once submerged in water, salted cod behaves like fresh fish and can enter the food safety “danger zone.”
• Not changing the water: fresh water draws out more salt and keeps flavor balanced.
• Boiling too aggressively: a hard boil can toughen the fish and affect texture.
• Skipping the taste test: always test a small piece before cooking. You can add salt later, but you can’t remove it.
• Not removing skin and bones after soaking: Cleaning the fish properly ensures better texture and presentation in finished dishes.

These small details make a big difference in final flavor and texture.

After Soaking: Next Steps

Once properly desalted:

1. Drain and pat dry.
2. Remove skin and bones.
3. Flake the flesh using your hands or a fork.
4. Use immediately in your recipe.

The fish is now ready to sauté with onions, thyme, garlic, peppers, or folded into your favorite Caribbean dishes.

How to Store Desalted Codfish

• Refrigerate soaked codfish for up to 2 days.
• Keep in an airtight container.
• You can freeze desalted codfish for up to 1 month. Be sure to squeeze out excess water and pat it dry before freezing to preserve texture.
• Thaw in the refrigerator before using.

Never refreeze after cooking.

Where to Buy Salted Codfish

Salted codfish is widely available in:

• Caribbean and Latin grocery stores
• Mediterranean markets
• Some Asian supermarkets
• Larger supermarkets in the international foods section

It may be labeled as bacalao, morue, or salt cod. Look for firm, heavily salted pieces with no strong odor.

If buying vacuum-sealed packages, check the expiration date and avoid excess liquid in the packaging.

Tools for Desalting Codfish

To properly soak or boil salted codfish, you’ll need:

• Large glass or stainless steel bowl: Big enough to fully submerge the fish in fresh water.
• Large pot: For the boiling method.
• Fine-mesh strainer or colander: To drain and rinse thoroughly.
• Paper towels: For patting the fish dry before cooking.
• Food-safe disposable gloves (optional): Helpful if you prefer not to handle salted fish directly.
