I was a little surprised to see this in my newest Penzeys Spices catalog--a column explaining that Penzeys will
"no longer be selling the higher priced specialty salts. I [Bill @ Penzeys] feel things have gotten to a point where the specialty salts are glamorizing the use of salt and, with that, encouraging people to use more of it. I have also found that along with the marketing of specialty salt has come a great deal of misinformation, including claims that some salts don't affect your health like others do. This is just not true...salt is salt..."
I haven't tried too many salts, but thought some Chowhound readers here would be interested to see this.
They will continue to sell only "reasonably priced genereic salts of the sea and earth."
