Kosher salt (sodium chloride) is one of the most commonly used salt in commercial kitchens today. Kosher salt, unlike common table salt, typically contains no additives (for example, iodine). Kosher salt has a much larger grain than regular table salt, and a more open granular structure...Chefs often prefer kosher salt because its texture allows the chef to pinch a larger quantity of salt and evenly sprinkle the flakes on food.
