Ah but we digress yet again, so back to the curries in the OP and questions that again threaten to derail the post;
By comparison to say Kashmiri or Jalapeno, how destructive are the Naga chili?
What is the reasoning behind the fascination that curries must be "hot"? I understand that some should be and actually need to be but not all BIR dishes are lip blistering, are they? (Remember, I'm on the other side of the planet and certainly out here not all curries are hot.)
