Kosher salt

Koshering salt, usually referred to as kosher salt in the US, is a variety of edible salt with a much larger grain size than some common table salt. Like common table salt, kosher salt consists of the chemical compound sodium chloride.

Unlike some common table salt, kosher salt typically contains no additives such as iodine, although some brands will include anticlumping agents in small amounts. Additive-free nonkosher salt is also readily available. The Salt Institute claims "Kosher salt contains no additives".

Name

The term "kosher salt" derives not from its being made in accordance with the guidelines for kosher foods as written in the Torah (nearly all salt is kosher, including ordinary table salt), but rather due to its use in making meats kosher.One salt manufacturer considers the term ambiguous, and distinguishes between "kosher certified salt" and "koshering salt". "Koshering salt" has the "small, flake-like form" useful in treating meat. "Kosher certified salt" is salt that has been certified as such by an appropriate religious body.

Manufacturing and use

Rather than cubic crystals, kosher salt has a flat platelet shape. Salt crystals are forced into this shape under pressure, or grown flat in an evaporative process. Kosher salt is usually manufactured with a grain size larger than table salt grains.<ref...
