This classic bayou favorite can be adapted for all sorts of seafood or sausage. A reliable crowd-pleaser for cajun fans.
Heat oil in a large black pot. Add flour to oil. Make a very dark roux in a large heavy pot. Add onions and garlic. Cook slowly until onions are transparent. Add tomatoes and cook on low heat until oil rises to the top (about 30 minutes) stirring frequently. In a separate skillet, fry okra in oil on moderately high heat, stirring constantly until okra is no longer stringy. Add the okra to the other mixture, stir and simmer about 10 minutes. Add water, salt and pepper. Simmer partially covered for 45 minutes. Add other seasonings and simmer an additional 20 minutes, then add shrimp-simmer 15 minutes; then add crab meat, simmering 15 minutes more. Add the oysters the last 5 minutes of cooking. Taste carefully for seasoning, adding more if necessary. Remove from fire and stir in green onions and parsley.
Serve over rice. Variations may be made by adding different seafood, sausages or poultry. Serves 8-10.
