You Don't Have to Preheat Your Popcorn Oil

I always pop corn the same way. I'll add a lot of oil to the pot, sprinkle in three (3) test kernels and heat them over medium-high heat. Once those test kernels have popped then-and only then-would I dump in the remaining popcorn. It turns out those test kernels were completely unnecessary.
