Many American friends are stumped when I ask them about traditional American fare. Americans have had exposure to global cuisine for a long time thanks to immigrating people from every corner of the world; in fact, many would consider Italian staples such as pasta American. I recently discovered an article on the Best American Food at
Conde Nast Traveller by Alan Richman that made me smile. This is how he begins:

Before we were able to pay attention to food, Americans had to perfect democracy, settle the West, free the slaves, crush the Nazis, and fight the commies. Meanwhile, we ate whatever was at hand. We stewed squirrels. We turned turtles into soup. Food was secondary. Oh, we had raw materials aplenty: fields of waving grain, herds of juicy protein, oceans of non-farmed fish. We just didn't know what to do with it all.

Our first uniquely American restaurants appeared in the fifties and sixties. We called them Polynesian, even though none of us knew where Polynesia was or what Polynesians ate. We concocted Sesame Chicken Aku-Aku and Shrimp Bongo Bongo. It was our first date food. In the seventies, food started to change, courtesy of a place we had never taken seriously before: California - home to Alice Waters and Wolfgang Puck, fresh vegetables and wood-grilled meats.
Once we discovered how much fun it was to eat, there was no stopping us. We freed chickens from their pens - and ate them! We let pasta get cold - on purpose! We shunned preservatives that prevented spoilage - and called it health food!”
