salt cod

Salt cod, known as bacalao in Spanish and Portuguese, morue in French, and baccalà in Italian, is Atlantic cod (Gadus morhua) that has been preserved through salting and drying—a process dating back to medieval times. The cod is gutted, split lengthwise, and layered with salt to draw out moisture, then air-dried to form hard, pale fillets with a distinctive crystalline crust. The resulting product has a firm, dense texture when dried, and requires rehydration through soaking before cooking. Different regional styles exist, including the boneless, skinless fillet (most common), split fish with the backbone intact (popular in Southern Europe), and shredded forms used in specific dishes.

Salt cod is a cornerstone ingredient in Mediterranean, Portuguese, Brazilian, and Caribbean cuisines, with historical significance as a staple protein during maritime exploration and trade. It is most famously prepared as bacalao à Brás (shredded and fried in Portuguese cuisine), bouillabaisse (in Provençal fish stew), brandade de morue (creamed salt cod from Southern France), and in countless Portuguese and Spanish preparations. The ingredient's strong, briny flavor and gelatinous quality when reconstituted make it ideal for hearty soups, thick stews, and creamed preparations. Desalting typically requires 24–48 hours of water changes, after which the flesh becomes tender and absorbs flavors well. It pairs excellently with potatoes, chickpeas, olive oil, garlic, and tomatoes.
