The forum of late seems to be covering the same old things regards "the taste".
Every other post is about the taste and the ones that arn't end up being about it, with just speculation and maybe's suggested.? As you say everyones perception of "the taste" is slightly different which is why I think were going round in circles.?
I think I can produce a restaurant tasting vindaloo, now if you've tried my method and didn't im either lying, your not making it right or my local takeaways produce crap vindaloo's so that to me mines better.? Ive never had a vindaloo with spring onion, tomato or fresh chilli(unless asked for) in for a start, you see what im saying.? To me a vinaldoo is prefried onion(one place i go to has this so optional), garlic & tom puree, base, chicken & potato, restaurant masala and chili powder with corriander thats it.? Theres no secret ingredient apart from a good base and spice mix.
I think the only way forward is to get more recipes from chefs, the more further afield the better, to get a bigger picture rather than guessing at some fabled secret method that NO ONE IN THE WHOLE COUNTRY SEEMS TO KNOW? ;D
Just to add, of the four places I order vindaloo 2 of them are better than mine without a doubt, one of them I would say about the same, it varies and the last place I prefer mine.? To me thats not bad going given that your average restaurant chef probably cooks more currys in a week than I have in the last 2 years!!
