Lent and cod: why it became the star fish (and how to choose it well)

The origin of a thousand-year-old tradition

The connection between Lent and cod dates back to the early centuries of Christianity, when the Church established periods of fasting that prohibited the consumption of meat. During these forty days of penance, fish became the main source of protein in millions of European households.

Cod gained prominence for a fascinating practical reason: its ability to be preserved through salting allowed it to be stored for months without refrigeration. North Atlantic fishermen developed curing techniques that transformed this fish into a long-lasting and nutritious food.

By the 15th century, the Basques already dominated the routes to Newfoundland, turning cod into the "white gold" that fed Europe during periods of abstinence.

Why cod conquered Lenten palates

Exceptional culinary versatility

The cod tradition has been consolidated thanks to its extraordinary culinary adaptability. This fish lends itself to countless preparations: from the classic cod in pil-pil sauce to innovative contemporary creations. Its firm texture and delicate flavor have made it the perfect canvas for regional cuisines.

Spanish families developed recipes that made use of every part of the fish. The bones were used for broths, while the thinnest flakes were reserved for omelets and croquettes.

Unmatched nutritional value

During periods of abstinence, cod provided high-biological-value protein, B vitamins, and essential minerals such as phosphorus and potassium. Its low fat content made it ideal for prison practices, without sacrificing the necessary energy intake.

The ultimate guide to choosing quality cod

Fundamental visual criteria

When buying salted cod , visual inspection is crucial. A premium specimen has a uniform whitish color, without any yellowish spots indicating oxidation. The surface should show well-distributed salt crystals, a sign of proper artisanal curing.

The thickness of the pieces reveals the quality of the original fish. The thick loins come from adult specimens caught in cold waters, where they develop better muscle mass and flavor.

Decisive geographical origin

The best cod come from the frigid waters of Iceland and Norway. These areas offer ideal oceanographic conditions: low temperatures, plankton-rich currents, and rocky bottoms that promote the muscle development of Gadus morhua .

Origin Characteristics Optimal season
Iceland Firm texture, intense flavor January-April
Norway Large flakes, fine salt February-May
Newfoundland Delicate fiber, traditional curing March-June

Advantages of buying dried cod online

Buying dried cod online offers significant advantages for the discerning consumer. Full traceability allows you to know the exact origin, catch dates, and processing methods used.

Online specialists maintain optimal storage conditions, controlling temperature and humidity to preserve organoleptic properties. Furthermore, vacuum packaging guarantees preservation during refrigerated transport.

Practical tips for the savvy consumer

Desalting is the most delicate process in preparing cod for Lent . Improper soaking can ruin even the best product. The general rule is 24-48 hours, depending on the thickness, changing the water every 8 hours.

  • Check the flexibility of the flakes before desalting
  • Use cold water to maintain the texture
  • Test the salt level by tasting
  • Keep refrigerated after desalting

Do you need personalized advice to choose the perfect piece? Experts at specialized cod shops offer guidance based on the dish you plan to prepare, adjusting the cut and presentation to your specific culinary needs.
