Christine,
There was an article in the San Jose Mercury News Food section recently.
A very well known chef was cooking a vegan gormet dinner for Hillary
Clinton.
He replaced the anchovies in his ceasar salad with a small amount of
(Dead Sea? Red Sea?)
sea salt. It comes in very small amounts and is said to be VERY
flavorful, both tangy and salty. It sounds as if it may be what you are
looking for.
