I love Pop corn but am appalled at the amount of fat in most microwave brands. Not to mention my microwave is cooking very unevenly lately. I bought some store brand popping corn. Put some oil in the bottom of a heavy pot, coverend the bottom with corn, popped it. Like I have done many times beofre BUT this time, the kernels were only about 1/2 popped and by that I mean all of them popped but only 1/2 way, like mostly kernel with just a little edible peice around the edge. Do you think it was the quality of the corn or what??? This has never happened to me before.
