I had an idea the other day, but it might be utterly stupid. The trouble is, it's burning a hole in my head, so I've got to tell someone (and who better than you lot?!

).
I've always thought that the overpowering smell in restaurants came from the tandoor. And I've thought that the bought curries I like best have this aroma about them. The puzzle being, that we know meat for the plain curries (i.e. not chicken tikka vindaloo) isn't cooked in the tandoor. It's impractical.
We know that at least some restaurants/takeaways use a chicken stock in their bases. Pete's seen something added to his dish which he was told was 'balti paste' but which he now thinks - on reflection - might have been chicken jelly. So (takes deep breath and waits for howls of laughter):
Is there any reason, d'you think, why some kitchens might make a chicken stock...
...from chicken cooked in the tandoor?
Somebody said here (sorry, can't remember who) that stock made from roasted chicken was richer because the bones caramalised on the oven. Somebody else said that the tandoor meat was cooked during the day, as the temperature of the oven needed to be lowered for breads and kebabs during the evening. So if there was unsold tandoori chicken in the fridge at the end of the day, could it end up in next day's stock?
Or have I just boiled my brain with home-cooked vindaloos each day for the past week?!
