My favorite:
risotto: rizz-OT-Toh - an Italian rice dish that can be served as a starter or main course. Risotto should never be served to Chef Gordon Ramsay unless the cook making it is absolutely certain that the dish is made correctly. [Some people] have an annoying tendency to pronounce the dish, incorrectly, as rizz-Owe-toe and need to get a clue.
(edited to remove incorrect generalization)
