we must all remember that not all great curries derive from using just base..........
I would think that no one would disagree with that 976bar. It's just that all great "
traditional British Indian Restaurant (BIR)" curries are made using a curry base!

By "traditional BIR", I mean those Indian restaurants that proliferated, in Britain, in the 1970s and 1980s, and which were predominately Bangladeshi owned and run.
In my opinion, "traditional BIR" cooking is typified by the use of a pre-prepared curry base (and other pre-prepared ingredients, such as meats), and by other cost/time saving ingredients and techniques, in order to bang out a relatively wide range of curries, relatively quickly, at a relatively low cost.
Of course I should have said that time=money too.
On the other hand, "authentic" Indian cooking does not make use of a pre-prepared curry base (the "curry base" can probably be considered to be done, "in situ" i.e. when making the curry) and makes more use of exotic ingredients (e.g. whole spices and freshly roasted and ground spice blends) and techniques (e.g. marination, slow cooking, etc).
I have never done a comparison of volumes, costs and delivery times of "traditional BIR" restaurants versus "authentic" Indian restaurants, but I suspect the latter would always be slower and more expensive than the former; albeit equally delightful.
It is "traditional BIR" cooking (i.e.
WITH a curry base) that this forum is primarily focused on (or certainly has been), rather than "authentic" Indian cooking (i.e.
WITHOUT a curry base).
Upon reflection, I think the answer to your original question ("If money was no object, would they be making curries using a base? or would they adopt a different method?") is "yes"! If time and money (and the Western pallatte!) were not factors, I think they (i.e. Indian restaurants) certainly WOULD use different techniques....and undoubtedly use a more "authentic" Indian cooking style. It is pretty well known that many restaurant staff generally prefer to make and eat their own dishes, using different ingredients and techniques, rather than the dishes on their menu.
"The Bombay Brasserie" promotes its food as "authentic Indian flavours transformed into a contemporary gourmet experience"....using "exotic international ingredients and traditional techniques".
Yes, to my mind, it is a
VERY "posh" Indian restaurant (they even say "Sir Anthony Hopkins, Will Smith, Prince Charles, Tom Cruise, Mick Jagger, Nicole Kidman, Goldie Hawn, Tom Hanks, Bruce Springsteen, Mel Gibson, Danny DeVito and Sir Elton John are just some of the famous faces that have become fans of Bombay Brasserie over the years!")! Curry leaf scallops on tomato chutney starter anyone (for around 11 quid)? Or how about duck with kumquat and ginger chutney (for only 22 quid

)? No? Then what about apricot and potato cakes with yoghurt and taramind chutney? And not a madras, vindaloo, phal, jalfrezi, rogan josh, etc, in sight! They even garnish their curries with CHERRIES and STRAWBERRIES ffs......! :-X
This restaurant is a clearly differentiating itself from the more "traditional BIRs" (from which it is about as far removed as you could possibly get!). I'm pretty sure more and more Indian restaurants will do so, as palettes and demands change, and to capture niche markets (not to mention the rich and famous with very deep pockets!

).
