I love this salt and use it on my french fries as well as on popcorn.  It is not as good as fleur de sel or some of the other "gourmet" salts, but it is only 15 cents per ounce, not 15 dollars.  Note that this salt is flaked, unlike the normal crystals for which Diamond Salt is known.  It absolutely CLINGS to the surface of the popcorn, fries, and other similarly-textured foods MUCH better.  It has a cleaner taste than some of the brown or grey sea salts and CLEAN is always good in my book.
