No self-respecting Indian would use "curry powder" in cooking. To Indians, it is as absurd as throwing some rosemary, oregano, thyme and basil together, bottling the mixture, and calling it "Italian powder," to be used in making pasta, veal and fish alike, as though any dish would become Italian by the use of this mixture.
Hate to tell you, but India is making spice mixes of its own, packaging them, and shipping them to every Indian grocery store where NRI's (do they have no self-respect?) insist on buying for staples for home cooking. I don't think it is regarded as a matter of self-respect that you grind and mix your own curry mixture. And the labels on these packages say "curry powder". Granted, it isn't what Schilling has been selling for a hundred years or more, but it is what India seems to think is the more authentic form of the product.
