A few years back I was at a garage sale and found an old top-of-the stove popper with the handle that you crank as the popcorn pops. Magnet sticks to the pot, so I tried it on the induction stove. It makes the best popcorn in 2 minutes. And I don't know how "efficient" IR radiated poppers are, but 95% of the energy I put into the induction stove goes into the pot.

My wife still buys her microwave popcorn, because she hates washing the popper pot. I don't understand why it's so difficult. Wipe it out with a paper towel and put it away.
