I do agree that if the raw pastes don't taste the same, there is no chance of dishes cooked with them being even similar. I still maintain that the tasting of the raw pastes is no guarantee of successful reproduction. Of course if the original propriety product paste has a complete ingredient list with percentages, then the chance of reproduction is significantly inceased. I'm not saying that you havn't landed a copycat version. You probably have. I'm simply questioning the reliability of using raw taste tests as an indicator.
The concentration of the paste and nature of it would blast the taste buds, along with fact that raw spices, in most cases, taste nothing like cooked.
I'm sure you've also cooked the pastes as well for comparison.
Past experience in trying to replicate products has shown me that even when most ingredients are known, the home made item is rarely exactly the same. Food product manufacturers have access to additives and preservatives that aren't found in kitchens or on supermarket shelves.
