Sometimes I get a little nervous when dealing with hot oil for popcorn. If it gets hot too fast and I'm not moving the pan around, kernels can burn pretty quickly. And, it's a bit tedious to stand at the stove shaking the pan. Here's simple solution to know just when the oil is hot.
Next time you make popcorn on the stove, after pouring oil (vegetable oil, peanut oil, or other oils capable of high heat) in the pan, crank up the heat and add 3 popcorn kernels. Let the oil heat up with the lid ajar. Once one or more of the kernels pops, then add the rest of the popcorn. This way, you don't end up standing at the stove and you know exactly when the oil is at prime popping temperature.
