Also, there appears to be something hotter than ghost peppers (avg. 1.041 million SHU):
Carolina Reapers, which clock in at around 1.5 million SHU. For reference, habaneros top out at around 350,000, and jalapenos top out at around 20,000. Almost 100x hotter than a jalapeno. My friends, I think I have found a new comrade.
