Salted cod, also known as bacalhau in Portuguese, is a type of fish that has been preserved through salting. This method removes moisture, which helps prevent spoilage and extends the fish's shelf life. Salted cod is commonly used in various cuisines around the world, particularly in Mediterranean and Scandinavian dishes. To prepare salted cod, it must be soaked in water for several hours or days to rehydrate and remove excess salt. Once rehydrated, it can be cooked in a variety of ways, such as baking, frying, or boiling. Salted cod is rich in protein and has a firm texture, making it a versatile ingredient in many recipes.
