I don't like the flavor of pain. They have to be hot but not insane.
Jalapenos are the hottest I like. After that, there is little flavor and just hot. When I drank booze, I could take a lot more heat. Not any more. I like hot, but not insane.
Black pepper and ginger are my favourites. Sometimes raw garlic. A tiny smear of wasabi. A little mustard. If it's chilli is has to be super mild or I can't cope.
