Sea salt is a general term for a range of gourmet salts produced by evaporation of ocean water or water from saltwater lakes. It's generally less refined than other types of salt, so it retains trace minerals that lend it a variety of tastes, textures and colors.
Sea salt is typically named after the region it comes from. Sea salt is often promoted as a healthier alternative to table salt, but by weight, it has a comparable amount of sodium. Some sea salt may also have iodine.
While sea salt may be used in baking and cooking, some cooks reserve it for final seasoning of dishes to better appreciate the flavor and texture.
