Differences Between Rock and Table Salt
Many people use salt products without giving too much thought about the similarities and differences between the two. Here are common similarities and differences between rock and table salt.
Both table salt and rock salt are formed from the same base, which is sodium chloride. At a minimum, manufactures typically add the following to their table salt products:
- Anti-caking agents
Table salt manufacturers add iodine to table salt to prevent us from developing an iodine deficiency. Anti-caking agents keep the individual salt crystals from sticking together. Beyond these additives, the main difference includes the size of the grain used in each salt. Table salt grains are much smaller than rock salt grains. By the time table salt reaches consumers, it is finely ground and requires no further processing. In other words, no further processing is necessary before applying to food or using it in a recipe.
Rock salt forms from sodium chloride, however, the grains are much larger than those of table salt. The grains require further work before use in food preparation. Traditionally, rock salt was used for purposes outside the kitchen, such as ice removal. Today rock salt is becoming more and more favored in kitchens across the globe. Pink Himalayan rock salt is becoming very popular due to the high trace mineral content. In addition, salt grinders make it possible to grind food-grade rock salts down to appropriate salt servings.
