It is so simple I was sure it wouldn't work. Microwave popcorn bags are filled with food-like substances that ensure the popcorn pops and there is some sort of lining in the bag that super heats or something. Maybe there is, but not needed my friends.
I took a plain, brown, paper lunch bag, filled it with 1/4 cup of popcorn kernels, folded the top of the bag down twice and put in the microwave for 4 minutes. I stood and listened for when the popping slowed down and stopped it then (it was around 3:30). It took a little longer than conventional microwave popcorn to start popping, but don't panic. How did it taste? Heavenly. I was sure the folded top would not hold causing kernels to pinging all over the microwave or there would just be a black, smoking mass of kernels in the bag...no to both presumptions.
So as stated above the recipe is pretty plain, I wanted to try bare bones to see if it worked. You can coat the seeds in olive oil prior to popping and add a pinch of salt after or dress as you like. Keep in mind the popcorn itself is low in calories, it is the additions after than can add up. Three cups of plain popcorn has 3.5 g of fiber (insoluble fiber which keeps you pooping) and only 93 calories. A great choice for an after dinner snack.
So get out your dental floss and become your own paper bag popcorn prince or princess!
