Gone are the days where prospective moviegoers would roll up to the theaters and gawk at the board for their next watch. Theaters are trying to make up that business in other ways.
movie theater popcorn is super easy to make yourself with something like this. you can of course get all the components separately as below, but the all in one packs are a convenient way to try it out.
for 1 medium-ish bowl (easily doubled if you have a big enough vessel):
1/3 cup kernels (Orrville Red. works for me, the main thing for good popping is fresh kernels)
I know a lot of people swear by the stovetop method, but if you're the kind of person who would somehow manage to burn cereal, a Whirlypop is 30 bucks well spent. Way fewer unpopped kernels than mocrowaving, and it stirs everything from the bottom so it's almost impossible to burn.
