Personally, I'm not sure what drives me. There is some pleasure obtained from the heat and the senses it creates. I had a vindaloo last night which isn't a dish I order very often, but I figured I wanted to see how other restaurants made their vindaloo and whether there would be a noticeable smell/taste of vinegar, which I am not a huge fan of. I noticed some hiccuping upon starting to eat the dish, which is something I saw mentioned on here with regards to heavy heat curries but never noticed happening to me in the past and I was mostly happy with the food I had. Heat level was just spot-on. But I got to be honest, since reading CH's phall recipe that I feel like giving it a try.
