Kosher salt is free of iodine, and additive-free.
no
Most salt is kosher by default unless additives such as flavourings are added, at that point the salt would have to be certified kosher. 'Kosher salt' refers to a large grain salt that is used during the process of kashering meat. Iodized salt is kosher.
Yes
Yes, you can. Kosher salt is the same as table salt, only a larger granule.
Non-iodized flake salt, also sometimes called "cheese salt". Salt in cheese is used both to give flavor and to preserve. Iodized salt has iodine in it which hinders some of the bacteria you want in the cheese. You can use kosher salt or any natural, non-iodized salt that is in a flaked form.
Generally it is not, but check the label to be sure.
Yes.
Iodized salt usually is a form of processed table salt, of which the grains are very fine (about 1/8 of a cubic millimeter each). Kosher salt (iodized or not) is salt that is used for koshering meat. Its grains are considerably larger than those of table salt (though sizes of Kosher salt grains vary).
By default, salt is kosher unless something is added to it to make it not kosher - usually flavourings. Kosher salt may or may not be iodized, you'd have to check the label on the package to be sure.
Yes, non-iodized salt can conduct electricity because it contains sodium and chloride ions, which are free to move and carry electric charge. The conductivity of non-iodized salt is lower compared to iodized salt because the added iodine in iodized salt can slightly enhance its conductivity.
The recommended alternative to iodized table salt for seasoning dishes is non-iodized fine-grain sea salt.
Iodized salt helps prevent goiter and mental retardation. The non-iodized salt helps maintain the color and texture of pickled food and it does not affect the taste of food when cooking.
