I bought a new popcorn maker recently and it’s the best I’ve ever had. It works like this one:
You put a couple teaspoons of oil in the bottom, then 1/4 cup of popcorn kernels, put the cover on and turn it on. A metal rod that sits on top of the hot plate revolves, mixing the kernels so they don’t burn. Within a few minutes it’ll start popping. It’s quiet – just a low hum for the motor that turns that rod. EVERY kernel will pop if you have good kernels.
The popcorn maker costs about three times as much as the cheap air-blown ones, but it’s worth it.
