Follow your manual for the size of popcorn machine that you have. NOTE: The KEY is using butter flavored coconut oil, popcorn, and flavacol to get the same great flavor as movie theater popcorn.
Dump the popcorn kettle when it begins overflowing. Always turn the kettle off after dumping unless you are making another batch of popcorn.
Notes
Popcorn machine is a great investment for movie night or large gatherings where popcorn can be made in large quantities to be enjoyed by all.
