We have been looking for a healthy popcorn salt that tastes like the theaters for a long time.  I came across this powdered sea salt and it was exactly what I was looking for.  Sea salt is good for the body with trace mineral content, but in it's regular form would not stick to the popcorn.  This sticks to the popcorn and tastes makes it taste just like the theater popcorn.  I love this and will use it on other foods as well.
