1.
Koshering salt, usually referred to as kosher salt in the US, 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 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 (for example, iodide), although some brands will include anti-clumping agents in small amounts. Additive-free non-kosher salt is also readily available.
