Where did the term Kosher Salt come from and how does it differ from regular salt?

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, allowing fluids to leach out of the meat.

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, iodine), although kosher salt produced by Morton contains sodium ferrocyanide as a free-flow agent.
