My friend P. sent me this response to my story on chilli-heat. I thought you would love it too.
"I have a couple of friendly neighbours, one half of whom is a senior police detective who has a pepper spray as part of his standard issue kit. He complained over drinks one night that he hopes it still worked if ever he needed it in a crisis, because his partner is in the habit of using it from time to time to pep up a curry or a chili con carne. She said a couple of squirts from the pepper spray is a lot easier than chopping fresh chillies by hand - and it tasted just fine. Shame to waste such a handy culinary item on felons and ne'er-do-wells, in her opinion.
