Rock salt, also known as halite, is a type of mineral that is composed of sodium chloride. It is commonly used for deicing roads and sidewalks in winter, as well as for preserving food and seasoning various dishes. However, there are other terms that are sometimes used interchangeably with rock salt. These include table salt, sea salt, kosher salt, and Himalayan pink salt. While table salt is the most commonly used type of salt for cooking and seasoning, sea salt is known for its natural minerals and flavor. Kosher salt, on the other hand, has a coarser texture and is often used in Jewish cuisine. Himalayan pink salt is said to have numerous health benefits due to its high mineral content.
