Duck and Oyster Gumbo

Preheat oven to 350 º. Liberally season the duck with salt and pepper. Slowly roast in pre-heated oven until most of the fat had rendered out and the skin is nice and crispy, about 1. 5-2 hours. Remove the duck from the oven and reserve the fat. Once cool, pick all the meat and skin from the duck, cut into roughly 1-inch pieces, and reserve. To make the stock, place the duck carcass in 2-gallon pot and add 1 cup onion, 1 cup celery, carrots and bell pepper. Cover with water and bring to a simmer. Let simmer 2 hours, strain, and reserve, yielding about 1 gallon of stock. To make the roux, in a pot, over low heat, heat 1 cup of reserved duck fat and flour together and allow it to slowly caramelize, about 1-1. 5 hours. Stir often and cook slowly over low heat to avoid burning. Roux should look like dark chocolate when finished. Add the remaining onions and the andouille and allow to caramelize further, roughly 5 minutes. Add garlic, Worcestershire, Creole seasoning, bay leaves and okra and simmer for 5 more minutes. Add the reserved stock and duck meat and allow to simmer for an additional hour. Add the oysters and simmer for 5 additional minutes. When finished, serve over rice in a large flat soup bowl and garnish with green onions
