Is there a difference between pickling salt and regular table salt.
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
Different size grains and pickling salt doesn't have added iodine, table salt does
Pickling salt is made without iodine or anticaking agents ("When it rains, it pours"). It's finer grained than table salt making it easier to dissolve.
Table salt may or may not have iodine added.
As an aside: when making cheese or fermented pickles such as sauerkraut or kimchi, do not use iodized salt. The iodine will kill the beneficial bacteria needed for fermentation. Use pickling salt, kosher salt, or sea salt (although you'll have to use different amounts depending on the coarseness of the salt.)
I did not know that, thanks. What I do know is that iodized salt smells funny and makes food taste funny.
Pickling salt also dissolves in cold water.
And - the lesson I learned the hard way -- Iodized table salt can turn your pickled product interesting colors. Learned when pickling garlic, used iodized salt (didn't know better) and the garlic turned a very interesting blue/green color. A fun science experiment, but never could bring myself to taste it...
Just a note about garlic being blue/green: Garlic contains anthocyanins, water-soluble pigments that turn blue, green or purple in an acid solution. While this color transformation tends to occur more often with immature garlic, it can differ among cloves within the same head of garlic. The garlic flavor remains unchanged, and it totally edible without bodily harm.
