I recently bought a "Windmere" hot air popcorn popper that I found used at the local Goodwill. I had been looking for one for a while and found them in short supply at ordinary department stores. It made me wonder, do they make pop corn poppers anymore? So, when I found this used one I decided that was the one.
The hot air popper has the advantage of not using oil and cleanup is almost non-existent. The only problem is that upon first use, despite using the plastic hood that normally would direct the popcorn down into the serving bowl, the popcorn was ending up all over the kitchen. Also, many of the unpopped kernels made it out of the popper early on. Upon subsequent popping attempts I used a cloth napkin fastened at the end of the hood to contain the popping corn and direct it into the bowl. This worked much better.
Of course any health benefit of cooking popcorn dry is mitigated by the drenching of melted butter and salt onto the popcorn. YUM!
