I have to say, that's one of the stupidest ideas I have ever heard in my life. Cooking is like playing music, there is no "right" way to do it. No two chefs flavour their dishes exactly the same way, and if they did, I don't think I'd ever eat out again. There is no such thing as: "BZZZZZZ! YOUR CURRY IS INCORRECT! ADD 5MG TURMERIC!", and part of the joy of cooking is allowing the flavor in a soup, sauce or curry develop the way you want it to as you taste it, think "hmmm, needs amchoor/hing/whatever" and take it in the direction you want.
