This guy definitely did not get enough exposure to American food. It's a huge country with a vast variety of regional cuisine as well as international dishes melded by the immigrants to match the American tastes.
Similarly, I visited a friend in France once. On the way there, I took the TGV from Paris. I don't remember anything special about that leg of the trip, and learned nothing about France. On the way back, we drove, and passed through a bunch of little towns. I have a fond memory of helping a boater open a gate to a canal lock, and I still have a strong impression of how contained French villages are compared to American ones.
Go to U.S. supermarkets or restaurant chains, you will find this is mostly correct.
Went to Olive Garden a couple of days ago, had some pork that was nicely cooked, but drenched in some kind of sugary syrup. It would have been much improved by eliminating the sauce entirely.
You even have to look closely at the ingredients when buying "Mexican" salsa or hot sauce. I sometimes get these home before discovering sugar on the ingredient list. Adding sugar to something meant to be hot and spicy totally perplexes me.
And I've lived here pretty much my whole life.
But, Americans aren't into subtlety...
