How to Prepare Salt Cod: Complete Guide

What is Salt Cod?

Salt cod (bacalhau) is one of the most iconic ingredients in Portuguese cuisine. It's Atlantic cod that has been dried and salted, a preservation method dating back centuries. This process completely transforms the fish's texture and flavor, making it firmer with a more concentrated, savory taste.

Types of Salt Cod

Dried Salt Cod (Traditional)

Traditional Portuguese salt cod is sold dried and stiff, looking almost like a wooden board. This type requires soaking before cooking.

Frozen Desalted Cod

Some stores sell cod that has already been soaked and frozen. This type is ready to cook after thawing - simply defrost in the refrigerator for 24 hours.

How to Soak Dried Salt Cod

The soaking process is essential to rehydrate the fish and remove excess salt.

Step by Step

  1. Rinse: Rinse the cod under cold running water to wash away surface salt.

  2. Submerge: Place the cod in a large container and cover completely with cold water. Store in the refrigerator.

  3. Position: Place the cod skin-side up. This allows the salt to sink to the bottom rather than getting trapped against the skin.

  4. Change Water: Change the water every 6-8 hours.

Soaking Times

Testing for Doneness
