Technique

Dry-curing (salting): Draws moisture out, preserving the fish and creating the characteristic salty flavor
Air-drying (wind-curing): Further reduces moisture and concentrates flavor without heat
Rehydration (soaking): Restores moisture and leaches excess salt before cooking
Poaching or pan‑frying: Provides final texture and develops surface flavor
Gentle simmering (optional): Ensures even cooking without breaking the flesh

Not changing soak water regularly
Using high heat causing dryness
Skipping the rehydration step

Provenance

Salt cod has been produced in the North Atlantic since the Viking era, with documented use in medieval Iceland and Norway. By the 16th–17th centuries it became a staple for long voyages and Catholic Mediterranean cuisines, especially in Italy, Portugal, and Spain.
