I too love the Hawaiian red salt, black lava salt and their jade green bamboo salt!
Cyprus pyramid salt flakes - in white & black - are my favorites too!
Pink salt with truffles (or any truffle sea salt) is in my top five, as is a good gray sea salt or smoked Chardonnay sea salt.
While coffee salt, and many flavored ones, and the elegant "Fleur de sel" are delicious and fun; the above mentioned are my favorite ones - and the blue Persian too! (It's compressed so much that hues of beautiful blue appear). In many of my threads on this site, I show the salt shaker and use that that salt.
Happy savory using to all! SALT CAN BE HEALTHY WHEN CHOOSING A GOOD SALT! Cheers! - Leah
