Salt salt is a salt used primarily for canning and pickling. It is sodium chloride, like table salt, but unlike most brands of table salt, it does not contain iodine or anti caking products added. A widely circulated legend suggests that iodisation causes the pickled salt water to change color. This is wrong; However, some anti-caking agents are known to collect at the bottom of the urn, a small aesthetic problem. Pickled salt is very smooth, to accelerate dissolution in water to create salt water, making it useful for solutions that require salt.

Other uses
Pickled salt can be used for other things besides preservation. It can be used in place of table salt, although it can be cake. The solution to this is to add a few grains of rice to the salt, or to bake (pull out the moisture), and then break it down. Pickled salt attaches well to food, so it can be used as a substitute for popcorn salt, which also has fine grains.
