Poutine is pretty much originated from where I live : Québec.
I don't see why USA would have good poutine to be honest.
The way it's made is pretty simple though. A simple Google would give you the answer.
Trying it out is a different story though... many fall in love with the dish, even though it's not really healthy.
If you ever want to try it, it's just 1,500 miles from where you live.
