Tip - Ask The Food Lab: Do I Need To Use Kosher Salt?

"More and more I see recipes specifying kosher(ing) salt or sea salt in recipes. I'm all for using gourmet ingredients but Serious Eats even proposes using sea salt to preserve Meyer lemons! Does there remain any use for which the much more affordable regular American-style iodized salt is preferred, or should I just use what I have left and only stock the higher-end stuff?"
