I grew up in the city that hosts the Missouri State Fair and I have a confession, I don't love that fair. Every year the fair would come to town with it's hoard of state troopers, tourists who didn't know which lane of traffic went where and nary an available restaurant seat to be had. Residents stocked up on supplies like a blizzard was coming or went to the lake for an extended vacation.
I also worked the fair as a teenager on those parking lot trams that, for 50 cents a person, would take you to the front gate. I did this for two years until I was old enough to get my first real job in fast food.

The key to good kettle corn is an oil popper with a stir stick. You can do this with a pot and spoon but be very careful since the sugar gets super hot. The rest is very simple. I've given the measurements in parts, with my measurements in parenthesis, so you can scale up or down to your tastes. Don't skimp on the oil, it helps keep the sugar from burning.
