The makers of my commercial-grade popper recommend coconut oil. Like you, I am interested in trying ghee. It's good to just have a bottle of that stuff handy for lots of things.
Also, people would stop getting angry at you for pooping outdoors.
Over the years I have twice seen our dog get nose-scratched by our cat (different cat/dog pair each time). In both instances, for the dog it was a moment of instant humility and respect.
My dog and his best pupper friend. Please come along and post your own!
The first time, simple stupidity. The second time? Future Darwin award-winner.
As I mentioned in a comment above, I have one of those theater poppers. But in those, the flavacol goes into the hopper right along with the kernels and your oil of choice. It's not an oil substitute. It's good stuff, but hard to find in less than 5-pound boxes.
