Yes, thanks for the report Chris.
Does this small scale base reflect what they do with their full scale base? I'd be surprised if they stand there and fry everything like that! I'd also be surprised if they spice it like that (with that much chili powder and chilies).
It sounds to me like this base was made specifically for your madras (with the extra chili and spicing to compliment it).
Other than that, the ingredients in the base look pretty much standard to me, apart from the yoghurt.
I'd tend to agree with whomever said that curry bases only differ slightly from place to place. They do seem to, with regard to the main ingredients. It's the peculiar things (such as yoghurt, margarine, celery, carrots, white radish, cabbage, potatoes, etc), which I can't really see you can adjust for in the curry recipe, that seems to be where the difference primarily lies.
I don't think you need the "correct curry recipes" to compliment a specific base. You just need to exercise a little prudence!
