I got this recipe from a woman I used to work with. The original recipe calls for 1 tablespoon paramount crystals, but recipezaar does not recognize paramount crystals (they can be hard to find). Paramount crystals thin the chocolate a little and helps coat the popcorn better, you can use parrafin or shortening in its place if needed. Also the bag size of natural popcorn is a complete guess (zaar wouldn't accept "bag of natural popcorn" ), just get the standard size bag not the mini bags.****** I don't have a microwave but I do have a popcorn maker so instead of buying a bag of natural popcorn I use my popcorn maker. There's about 5 tablespoons of popcorn kernels in a bag. I usually just pop a 1/4 cup just to make sure there's enough chocolate to smother the popcorn. And don't be afraid to get creative... I've cut back the amount of chocolate before and added a heaping spoonful of peanut butter, very yummy.
