We used Orville's popcorn for attempts 2 through 4 of getting movie theater popcorn at home.
It's producing a much larger and more consistent popcorn than the organic stuff. The organics aren't bad, but they're different. One advantage with the organic popcorn is the shells are a little thicker and don't get stuck in my teeth.
In attempts 2 through 4 I dialed in the amounts of corn, olive oil, and Flavacol.
8 heaping tablespoons of corn, 2 tablespoons of olive oil and 1/2 tablespoon of Flavacol seems to be the right ratio.
I've been told that coconut oil produces a more theater like flavor, but I'm concerned that it is not very healthy.
