I have been educated to see at least earlier uses of the artificial butter flavor in microwave popcorn as positively bad for human consumption, and so stick to high quality glass lid covered skillet with a bit of oil, and then douse with real butter melted in a microwave, so, got that part right, anyhow. Will surely check now on the brand, though, and thanks for posting it.
