What rock is used to preserve or season food?

The rock used to preserve or season food is called salt rock or halite. It is a mineral composed primarily of sodium chloride (NaCl). Salt rock is typically formed from the evaporation of ancient seawater and is found in underground salt deposits. It has been used for thousands of years as a seasoning and preservative in various cuisines worldwide. Salt draws out moisture from food, inhibiting bacterial growth and extending its shelf life. It also enhances the flavor of dishes and provides essential electrolytes for the human body.
