Flavacol 35oz. Popcorn Seasoning salt. Flavacol is the salt movie theaters use to make their popcorn taste the way it does! If you want to sell more popcorn, this is your secret ingredient! The fine salt flakes stick to the popcorn, whereas a ground salt will tend to fall off. Trace minerals that lead to a bitter taste are removed. Contains just the right blend of Yellow #5 and #6 colors to give popcorn a bright appealing yellow color — just right for maximum sales appeal!
