海盐, or sea salt, is a type of salt that is produced by evaporating seawater. It is commonly used in cooking and food preservation due to its natural mineral content and flavor. Unlike table salt, which is often refined and stripped of minerals, sea salt retains trace elements that can enhance the taste of dishes. The process of making 海盐 involves collecting seawater and allowing it to evaporate in shallow pools, leaving behind the salt crystals. This method has been used for centuries in various coastal regions around the world, making it a traditional and sustainable source of salt.
