more on popcorn - can you pop kernels that previously didn't pop?
i made my own microwave popcorn (kernels in a paper bag) but stopped the popping early because i didn't want to burn the popcorn. there were a lot of unpopped kernels left over. are these still useable? would they pop the way 'fresh' kernels would or has being under heat changed them somehow so that they won't work?
I have done it, just sift them out and have another go. Some may not pop because they are too dry and need the steam from inside to pop. If it seems that the rest are not going to pop within a reasonable time then pull it out and discard.
I do it all the time. I shake the bag as I take the popped corn from the top, until only unpopped kernels remain. Then I fold over the top and put it back in the microwave. Most of the remainder pop in 30 seconds or so.
After all, what's the worst that can happen? Any kernels that burn are those you aren't getting now.
They can pop again; however, when I put it back in the microwave, it seems like its dry and has a chalky texture. I put it in a pot with some butter, turn on the heat, and shake your pot constantly. It takes about 2 minutes max. Then season with your favorite seasonings. And the popcorn has tons of flavor, and isn't too dry as most of the oil and seasonings in the bag have been used up from the previous popping. If you don't want to use butter, you can use olive oil or any other type of oil you prefer.
