I obviously didn't mean that all the best cooks of all the myriad cuisines of the world are from a particular part of a particular state in southern India.
And I don't think that that's a realistic interpretation of what I wrote, considering I mentioned a specific south Indian state in a thread about a sub-cuisine of what could be loosely referred to as southern Indian. In fact, I think my use of the word "apparently" cautions readers to avoid concluding just what you did. Had I actually identified Chettinad cooks as the world's best according to a rigorous, objective, and quantitative process, I'd be writing a dissertation about it rather than starting a thread on an internet discussion board.
What I meant, and what I believe my posting of the Wikipedia excerpt clarified (leaving aside whether or not Wikipedia is a quality, objective source) was that people that live in southeast India (or who, for the purposes of LTH Fourm, otherwise consume and appreciate its cuisine) have a particular regard for the cuisine of Chettinad, as well as for the particular caste of people that create it.
I apologize if my desire to economize the length of my initial post and to avoid a discussion of the caste system has led to any confusion. For the record, I do not believe that Chettinad cooks are the best in the world, nor do I think that it would be possible or worthwhile to try to identify the particular group of people who might be.
