Pickling salt is a salt that is used mainly for canning and manufacturing pickles. It is made without iodine or any anticaking products added.[1] If pickles are made with table salt, they will have dark and cloudy juice, due to the iodide in the salt, although the flavour should be about the same. Pickling salt is very fine-grained, to speed up dissolving in water to create a brine, so it is useful for solutions needing salt.
Pickling salt can be used for things other than pickling. It can be used in place of table salt, although it can cake. A solution to this would be to add a few grains of rice to the salt, or to bake it (draws the moisture out), and then break it apart. Pickling salt sticks well to food, so it can be used in place of popcorn salt, which also has fine grains.[2]
