Bacalhau Salt Cod Processing

Cura do Bacalhau

The salting and drying of Atlantic cod (Gadus morhua) into bacalhau — the defining food of Portuguese culture. Portugal is the world's largest consumer of dried salted cod per capita; bacalhau has 365 traditional recipes (one for every day of the year according to Portuguese tradition). The cure transforms fresh Atlantic cod through a precise salting; pressing; and drying sequence into the rigid yellow-gold dried fish that can be stored for months and reconstituted by soaking. The curidor reads the curing progress by the color and texture of the dried fish surface.
