LOL!!!! Reminds me of my friend who boasted that he could eat the hottest curry in the world and not be affected. He was duly prepared a "special" - which was a triple phal. He won the bet, and was offered free meals of his choice, for a week. Unfortunately, the ultra-hot curry burnt his throat, literally, and after rushing to the loo, ended up with burns at both ends. I think your sprout vindaloo sounds much gentler on the system - and I shall recommend it!!
