The term "kosher salt" derives but not from its being made by recommendation for kosher food preparing. Nearly the all salt is kosher, including ordinary table salt, but rather due to its use in a process of meat kosher making: kosher salt extracts the blood from meat due cooking. Kosher salt has a flat platelet shape and ads with yellow prussiate of soda - sodium ferrocyanate. Because kosher salt grains are larger, while meat coated in kosher salt does not dissolve, but rather remains on the surface of meat, to extract fluids out of the meat, in a process of cooking.

If there is not enough liquid, the kosher salt will not dissolve sufficiently. In recipes where there is enough liquid to dissolve all the salt, table salt can be replaced by kosher salt, if volume gets to be adjusted.
