Salt should come from mines.
The sea salt craze has always seemed odd to me. Have most people in the USA never been to a beach? Do people really think that the sea is a good source of salt?
What I associate with the sea: seagull droppings, rotten seaweed, spilled oil, dumped WWII chemical weapons, raw sewage...
Then I go to the store and see a box of Triscuit crackers featuring sea salt. Yum??????
