Well I finally found out what this really is. I heard about it on Jerry Seinfeld. And I've always wondered wtf it was. Turns out it's nothing special, just a rice dish with sea food. Calamari, oysters or mussels, and shrimp and chopped up bell pepper. Mostly rice though. Usually with a chicken broth base.
Some people use chicken and sausage like in a gumbo, but to be authentic I think you would have to stick to sea food
It's pretty fucking good, why they made it out to be something mysterious is beyond me.
