, France.]] Sea salt, obtained by evaporating Seawater , is used in Cooking and Cosmetics . Its mineral content gives it a different taste from Table Salt , which is pure Sodium Chloride , usually refined from mined rock salt ( Halite ) or from sea salt. Areas that produce specialized sea salt include the Cayman Islands , France , Ireland , Colombia , Sicily , Apulia in Italy , and Maine and Cape Cod in the United States . Generally more expensive than table salt, it is commonly used in gourmet cooking and premium Potato Chip s. HISTORY Where Mineral Salt has been readily obtainable it has long been Mined . The salt mines of Hallstatt go back at least to the Iron Age . However, it has not been readily obtainable everywhere and the alternative coastal source has also been exploited for thousands of years. The principle of the production is the evaporation of the water from the Brine of the sea. In warm and dry climates this may be done entirely by solar energy but in other climates, fuel must be used. For this reason, sea salt production is now almost entirely an industry of Mediterranean and other warm, dry climates. The name normally used today for such places is salt works but the older English word is Saltern . An ancient or medieval saltern could be established where there was: " sea salt, Île de Ré.]]
In this way, Salt Marsh , Pasture (salting), and salt works (saltern) enhanced each other economically. This was the economic pattern in the Roman and Medieval periods around The Wash , in eastern England . There, the Tide brought the brine, the extensive saltings provided the pasture, the Fen s and Moors provided the Peat fuel, and the sun sometimes shone. The dilute brine of the sea was largely Evaporated by the sun and concentrated slurry of salt, sand, and mud scraped up. The slurry was washed with clean sea water so that the impurities settled out of the now concentrated brine. This was poured into shallow pans lightly baked from the local marine Clay , which were set on fist-sized clay pillars over a peat fire for the final evaporation. The dried salt was scraped out and sold. TASTE AND HEALTH Gourmands often believe sea salt to be better than ordinary table salt in taste and texture, though one cannot always taste the difference when dissolved. In applications where sea salt's coarser texture is retained, it can provide different Mouthfeel and changes in flavor due to its different rate of Dissolution . The mineral content also affects the taste. It may be difficult to distinguish sea salt from other salts with a high mineral content, such as pink Himalayan salt, or grey colored Rock Salt . Because sea salt generally lacks high concentrations of Iodine , an ion essential for human health Fisher, Peter W. F. and Mary L'Abbe. 1980. Iodine in Iodized Table Salt and in Sea Salt. Can. Inst. Food Sci. Technolo. J. Vol. 13. No. 2:103–104. April, it is not necessarily a healthful substitute for regular iodized table salt, which is usually supplemented with the element, unless another source of dietary iodine is available. Iodized forms of sea salt are now marketed to address this concern. SEE ALSO REFERENCES |
