I use a 3-quart pan, 3 T canola oil, 1/2 cup of Orville Redenbacher popcorn over high heat. I pour the popcrn in a paper bag, add salt (and sometimes some melted butter & honey), shake well, pour into a large bowl and serve it to myself. I never eat microwave popcorn. Has a cardboard after taste to it.
I just get the popcorn with that says movie theater type butter. I'm kind of a popcorn feign. I sprinkle Brewers Yeast on it as well, which is super healthy for you and taste great of popcorn and even sprinkle a little of the ground up parmesan cheese on it every once in a while.
