What's in your salt? No, seriously, have you ever looked? If you are using America's favorite Morton's, you are getting sugar. That's right, sugar in your salt. Salt, calcium silicate, dextrose, and potassium iodine to be exact. The calcium silicate is a "free-flowing agent".
If this gets under your skin like it did mine, you may want to consider switching to either sea salt or kosher salt. They are purer salts.
Kosher salt itself is not necessarily kosher. It is used in the curing process of kosher meats. It has mild flavor. It's flaky and adheres well to the rims of margarita glasses as well as fish. It doesn't contain the additives regular table salt has.
Sea salt is typically made from evaporated seawater. It too is free from additives.
Of course, I'm sure we all should cut down on our salt intake, but we don't need to be taking in more than we bargained for. Go for the simpler alternatives.
