Salt fish is a method of preserving fish by curing it with salt. This process removes moisture, which helps prevent spoilage and extends the fish's shelf life. Common types of fish used for salting include cod, herring, and mackerel. Salt fish is popular in many cultures and can be found in various cuisines around the world. Once cured, salt fish can be rehydrated by soaking it in water before cooking. It is often used in dishes such as fish stew, fritters, and casseroles. The flavor of salt fish is distinct and adds a savory element to meals, making it a staple ingredient in many households.
