I went to this incredible Caribbean style restaurant in Larchmont Village in Los Angeles called Prado. I had a dish called Pollo Negro which is a grilled chicken breast that comes with this incredibly complex black sauce that starts out sweet and finishes spicy. The texture is almost candy sticky/chocolate syrup like. To me, it tastes like cooked down beer, worcestershire sauce with pineapple and spices. It's really delicious.
If anyone here has had it, does anybody have any idea how to make it?
