...the origins of flavour is one of the big puzzle of our time and we don't have any solution yet...By reading it like this, it sounds like being a solved problem, which is not.

That is a very convincing argument, and it does hit a chord.

There is a fine line between simplification (so that all can understand) and accuracy, and here I agree, I kind of crossed it a little ;-).

Thanks for this excellent remark. I edited the text.
