I've been lurking here for a while, but I just came across something so frustrating that I needed to join and post.
For those who use the iconic Morton's salt AND/OR sea salt, stop. It has dextrose on the ingredients list. also, I'd avoid the salt shakers at all restaurants seeing as they probably use Morton's brand. I never thought my salt would have anything other than salt (or iodine) in it. I'm sure most people have switched to kosher or sea salt, but I just thought I'd share.
