Here's a quote from "Indian Foods: A Historical Companion" "The cuisine of Goa is an extraordinary amalgam of Portuguese and local sensibilities, mainly those of the Saraswath Hindus. Liberal use of vinegar (generally added to finish a cooked dish, since it turns bitter if added earlier), is essentially European, but use of various Indian ingredients, of of the less-spicy whole chillies of Kashmir and Goa (called bedige chillis in Karntaka) which impart an intense red colour, bespeak the local influence. ...vindaloo is a more liquid curry that used the dried rind of the kokum fruit to impart sourness." One of my memorable Indian meals was at a little restaurant in Rye. I asked for it to be very hot, and they brought out a curry that brought tears (happy, painful tears) to my eyes. David "Zeb" Cook
