Koshering salt usually referred to as Kosher salt in the USA, is a term that describes one of the most commonly used varieties of edible salt in commercial kitchens today. Kosher salt has a much larger grain size than regular table salt, and a more open granular structure. Like common table salt, kosher salt consists of the chemical compound sodium chloride. Unlike common table salt, Kosher salt typically contains no additives (for example, iodide), although kosher salt produced by Morton contains Yellow Prussiate of Soda a.k.a. sodium ferrocyanide as an anti-caking agent Kosher salt gets its name not because it follows the guidelines for kosher foods as written in the Torah (nearly all salt is kosher, including ordinary table salt), but rather because of its use in making meats kosher, by helping to extract the blood from the meat. Because kosher salt grains are larger than regular table salt grains, when meats are coated in kosher salt the salt does not dissolve readily; the salt remains on the surface of the meat longer to draw fluids out of the meat. The term kosher salt is restricted to North America; in the UK it is usually called "koshering salt", and in other parts of the world, "(coarse) cooking salt". In North America, the term koshering salt has been proposed as more accurate and is sometimes used in industry (e.g., The Salt Institute), but it is rarely used in everyday language.
