Flavacol is a very fine seasoned salt that sticks to the popcorn, whereas a ground salt will tend to fall off. Adding it to the oil as you pop improves the coverage without any fear of burning. This is the tried - and - true original popcorn salt! FLAVACOL is the worlds most popular seasoning salt. This "secret ingredient" adds buttery flavor & bright yellow color for real theater style popcorn. Because this salt is a fine flake, not a crystal, you only need to add a little right along with your popcorn kernels & oil and then pop. There's more of a "salt" sensation with less sodium.
