I agree. But I think a cook will believe that his favorite dish is the dish he cooks best, based on his preference.I beg to disagree, Packard.
"favorite" means "one likes most". If I asked someone who told me he could cook several dishes "What's your favorite dish", he might answer the dish he likes eating best.
So, the assumption is possible but there's also a possibility that one's favorite dish is not the dish he cooks the best.
This begs the question: Who is it that decides what dish he cooks best? Is he the one who decides, or other people he has cooked for? Maybe that's what we need to establish first.there's also a possibility that one's favorite dish is not the dish he cooks the best
