The tradition of salting
One of the most distinctive characteristics of cod is its preservation through salting, an ancient process that allowed its consumption throughout the year before the advent of refrigeration. This technique not only preserves the fish but also concentrates its flavors and modifies its texture, turning it into a unique product.
Salted cod is especially prominent during Holy Week in Spain, where it is part of deeply rooted culinary traditions.
The desalting process
Before cooking salted cod, it is essential to subject it to a desalting process that requires patience. The cod should be submerged in cold water for 24 to 48 hours, changing the water several times (ideally every 6-8 hours). This step is crucial to remove excess salt and restore the fish's optimal texture. Watch out for the mistakes you can make when desalting cod.
