Tip-
Use a stainless steel pot with no other materials. Heat your oven to 185. When popcorn is done popping move the pot without the lid into the oven to stay hot until movie time.
I actually got a job as the assistant manager at a movie theater a month before The Phantom Menace opened and I had to quit beforehand because I couldn't see in the pitch dark driving home.
Theater was closed for renovations and the manager pulled me aside after I cleaned the popcorn machines and said, "Holy crap what did you clean them with?" And I said, "A new toothbrush. They were filthy."
That was probably the last time they were clean.
@Shelter Yeah, I don't get it either!
I like salt and sometimes pepper or maybe a little olive oil and Old Bay.
Old Bay is so good on popcorn.
@Shelter I friggin love popcorn
That butter liquid crap they pump onto popcorn has always made me feel sick since I was a kid so I don't bother with it at all.
Also why would anyone want to soggy their popcorn?
