Interesting. I think I'd try an experiment on something like that and see if I could get those results too. Not that I enjoy super hot but just to see what happens. I like heat, but not so much that the intensity lasts forever.the nastiest burn I ever felt from a pepper was from a Thai hot pepper. I wouldn't say it was the variety of pepper that made it so hot but how it was grown. It was a root bound plant in a tiny pot but someone did something to cause it to have a massive amount of fruits. The fruits were stunted in size, I am not sure exactly what was going on to cause that but it was some sort of Bonsai type of deal. Then when all the fruits were ripe the plant was no longer watered and completely dehydrated. It was sitting in my parents house when I came to visit and I wanted to try one to see how hot it was. I had a Habanero about a month before that and thought i could handle any amount of heat on a pepper.
I Guess I handled it because I didn't die but it had such a dry unique heat that it burned hotter and longer than any pepper I have ever had. Although the Carolina Reaper I had a few weeks ago was Chemical Warfare type of hot and as hot.. the dry heat from the Thai Hot Pepper seemed to burn forever with no relief. I looked up the Scovilles on a Thai hot pepper and its really not Super Hot like some of the peppers I have eat since but I do believe the way it was grown somehow made that pepper as hot as it felt when I ate it.
We get Pho from a place here that has jalapenos hot enough to leave your lips burning. It could be because there's also hoisin and sriracha in it, but 2 slices of these babies raw is enough.
