I've been to Trapani (west coast of Sicily), and have even taken a little boat out to the Egadi Islands to bike around and eat good seafood.
The area around Trapani is full of salt flats which are windmill-filled.
You can buy their Sicilian sea salt on Amazon. Sure, salt is salt and "sea salt" is the same thing but it's fun to use their sea salt. I like the coarse type which does not fit in a salt-shaker. That's why we use salt bowls. I love salt.
