It was an accident but the "oil" they sell for the big popcorn poppers you see at carnivals? I got my wife a Whirly pop & thought that it duplicates the same motion of movie theater poppers & those other big ones so we gave it a try. Seemed to work well. The accident comes when my wife was saying it still didn't taste like the theater pop corn so I went in & melted some of the oil. I poured it over the pop corn & wow!!! Theater popcorn!! It may not be healthy (actually it's about as unhealthy as you get), but man does it taste good. Jim |
