I agree CK,
Over the years, I have moved away from freshly ground whole spices to commercial ground spices and curry powders. This is also in an effort to get closer to the BIR taste. I find that freshly ground spices are simply too aromatic and pungent. I find that commercial ground spices and curry powders produce a far more "diffuse" flavour, in comparison, and produce a taste more closely resembling that produced by a BIR restaurant.
