Sometimes people who use sea salt and write recipes forget to put the 'sea' in front. (Guilty...
)
Sea salt can be used at higher levels and provide trace minerals.
I believe that salt is like water. It's better to use it from the earth than to purify it to the point that it loses all of it's benefits. "Pure" does not always equal "good for you".
That said... I use the full amount... of SEA salt and am enjoying a piece as I read my weekend w. news.
