Yeah, the term ghost pepper is being used far too much. It's an insanely hot pepper, so you'd think a chip dressed in it would be super hot, but many things claiming it as an ingredient aren't even in the ballpark.
There's a quickie mart near me where they sell chicken wraps with ghost pepper mayo. It's kind of a joke. No hotter than a lot of black pepper, or maybe an average jalapeno.
All of the kids on my son's football team buy them and act tough as they eat them.
I made some real ghost pepper mayo using some dried Bhut Jolokias from my last veggie garden, and I gave a small container of it for him to bring to school for lunch.
He shared it with the team, and a few of the kids ended up going to the nurse, lol. I got an email from the school asking to please not do that again.
