Yes, I know it's not technically just methane, but methane is its primary constituent.
"Fossil gas" is also probably a suitable term, but I like "fossil methane" because it gets that spooky chemical name benefit.
Do you have the right pans? They're probably not thick enough.
Also, you don't have to let them heat up much at all. It basically uses magic to just make the pan hot, like, instantly.
