Kosher salt is regular salt that is named for its use in the preparation of meat according to the requirements of Jewish dietary guidelines. Kosher salt has half the saltiness of sea salt and is often the salt of choice in professional kitchens. It is a mined salt, free of chemicals and additives. It generally comes in flakes rather than granules. The flakes dissolve easily, and taste more salty than ordinary table salt. Due to the shape of the granules, there is simply less salt in a pinch of kosher salt than in a pinch of table salt. This is the kind of salt most often used on top of pretzels and on the rims of margarita glasses. Kosher salt comes in fine and coarse grain.
