Too bad my Megapop doesn't have buttered flavored salt.
My guest love the carmel stuff.
I pour in the oil let it get hot, then the salt and then the carmel stuff. (I think that's what I do). Look on the front of the carmel package, it says how to prepare the corn when using the carmel. It says you are not supposed to use salt but since my popcorn and salt is together, I can't separate it. This is what I'm using. My Dad gave me a ton of 12oz packs...
