With a cousin as a popcorn farmer, we go through a lot of popcorn. As in we buy 50lb bags at a time. I have a dedicated Wearever pan for popping. My dad gave it to us over 25 years ago. Like good cast iron cookwear, it is well seasoned and does NOT ever see soap and water. The pan is cleaned out after each use with paper towel. Anybody who is ever had popcorn at our place wants my pan. We have friends with a popper like the movie theaters but their kids will still request popcorn at our place.
I normally use just oil in the pan, but every once in awhile I use the Orville Redenbacher oil. We use popcorn salt to season, never table salt. We don't care much for the flavored salts, either. Once in awhile we do add butter to the popcorn. We also prefer white corn over yellow. Yellow just seems to pop with too many of the hull flakes that like to stick in between the teeth.
With family that grows popcorn as their crops, I grew up have popcorn as our nightly snack. It was no big deal for us to have popcorn every night and twice on Saturdays and Sundays as snacks. When we went to my grandparents, we sometimes got popcorn that was popped using lard instead of oil. Gave it a very different flavor. Haven't had it in years that way though. Not sure my adult taste buds would like it was well as my kid taste buds did.
