Yeah I would have thought by now non iodized salt would be a niche product or something you’d get at a pharmacy if you had a rare medical exception but the amount supplied indicates otherwise.
Alton Brown, my 2nd favorite tv cook/chef, almost always uses kosher salt. He prefers the flavor and texture to iodized salt. In his episode about salt, I think he comments that salt is so prevalent in most american diets that you are not missing out on the required iodine by using kosher salt when you use salt.
My 1st favorite tv chef, Steven Raichlen, almost always uses sea salt and he prefers a coarse grind.
