The hot chemical in black pepper is "Piperine" (C17H19NO3). As I have understood it, it is NOT "immunizing" as is capsicain. My own experience seems to confirm that. Lots of black pepper is still way hot, although I can stand the habs more and more. Anyone feeling they are becoming "immune" to piperine? Kristofer
