Admittedly I've never been to New York, or anywhere else in the states but I've generally heard of lots of the popular dishes, however, this I hadn't.
I came across it on the Chowhound forums.
If you scroll down, you'll find the recipes for the chicken, rice and white sauce. I used sriracha as the chilli sauce.
This was delicious. It was a bit faffy, having three different elements but not difficult, and so flavourful.
We both loved it and it'll become a regular here.
