Just remember if you say that sentence about any other country in the world it’s racist. Guess you’re lucky that the nation you think is filled with dumb people that can’t cook is America.
But you haven’t heard what I say about the English, for example. Or the Chinese.
And I do think there is great American cuisine — I have a close friend who is a chef who has been a pioneer in the field f American regional cooking. And I worship Tom Douglas. Which is why I deplore the urge to reduce great food and great ideas to nothing, when one more minute of slicing (or thinking) will get you the real thing.
