Ethiopian food is literally American? I thought it was, you know, Ethiopian.
What's next, pizza is American?
Haha, I'd tread carefully given the subject matter.
The unique element of American cuisine is that because it is a melting pot of various ethnicites that have adopted the US Nationality, they can bring their native cuisine and it would still be American cuisine given that those people are US Citizens. Kinda like how the UK adopted the curry even though that's clearly a South Asian dish. Immigrants from India/Pakistan who moved and settled into the UK introduced their native dish and its now become a common UK dish that sits alongside your steak pies, cottage pies and other british cuisine dishes.
Interestingly, there will still be a distinction between US Ethiopian food and Ethiopian food from Ethiopia given the cooking methods/ingredients used. Just like how UK curry isn't identical to Indian curry.
