From TFA:
One thing to get out of the way is that crab rangoon is not inauthentic, and you should not be embarrassed to order it. American Chinese food is its own cuisine, with its own staples and a reasonably long and fascinating history. There’s a fundamental problem with the concept of authenticity in food, because cuisine is constantly mutating and adapting to new ingredients, new people, new techniques, and new ideas. Mexican food would be completely different without the influence of the Spanish and Arab immigrants and colonists; the tomato is not native to Italy; the chili pepper is not native to Thailand. There are old dishes and there are newer dishes, and that can be an interesting distinction. And there is tasty food and lousy food, but using some concept of authenticity alone as a criterion is a flawed approach.
