CA I was specifically talking about the use of wine in pasanda here. It's definitely not a traditional ingredient of this very traditional dish. I wasn't saying that wine isn't used at all in traditional Indian cooking.
The vin in vindaloo (as I'm sure you know!) refers to the red wine from the barrels which were used to transport, and keep fresh, the pork. Of course the journey from Portugal to Goa is a long one and so, inevitably, along the way, the wine became more vinegary. This is why authentic vindaloo uses (or should use) red wine vinegar, for authenticity.
