OK, gumbo is stew, From Paul Prudhomme:
Egg and Dried Shrimp Gumbo
1 cup finely chopped onion
1 cup finely chopped green pepper
1/2 cup finely chopped celery
2/3 cup vegatable oil
2/3 cup flour
3 bay leaves
(1 teaspoon salt)
3/4 teaspoon white pepper
1/2 teaspoon black pepper
1 1/2 teaspoon Tabasco Sauce
2 (1 1/2 oz packages dried shrimp (3/4 cup)
7 cups seafood stock or water
1 teaspoon minced garlic
9 whole hard cooked eggs
1 1/2 cups hot cooked rice
Combine the onion, bell pepper and celery in a bowl. In large skillet, heat oil until it begins to smoke, about 4 minutes. Gradually add the flour, whisking constantly! until smooth until it is a dark red-brown to black, about 3-4 minutes. Be careful not to let it scorch, or splash on you! Stir in the vegetables and cook about 2 minutes, stirring constantly. Add the seasonings and Tobasco, cook another 2 minuts. Stir in the shrimp, cook another 2 minutes. Remove from heat.
Meanwhile, bring the stock and garlic to a boil in a 4 qt. saucepan. Stir in the flour mixture until the roux is dissolved, and simmer til shrimp are cooked. about 20 minutes. Add 6 of the whole eggs to the gumbo, cut the remaining 3 in half and add. Return to boil, remove from heat, let stand 10 minutes. Skim oil from top and serve over white rice.

And here is the Classic File Gumbo:
Melt in a skillet2 Tablespoons of butter Add and saute til brown a soup bone with 3 lbs. cubed beef.Add 12 cups water and simmer 2 hrs., Add 1/4 cup chopped celery
1/4 cup shredded parsley
1/4 cup chopped onion
1/2 teaspoon salt
1/4 teaspoon paprika
Strain, cool, and skim the stock. Melt 2 tabkespoons butter Add and saute 3 minutes 1/2 cup onion,1/2 cup okra,and 1 cup celery.Add:2 1/2 cups tomatoes,2 Tablspoons quick cooking Tapioca,1 Tablespoon sugar,the soup stock, and simmer 1 hour.Add 1-2 teaspoons file powder. Do not boil after adding file as it will become stringy.
I also have a recipe for Chicken gumbo that uses flour dredged chicken fried in bacon grease, sweet red bells,and rice. There is also mixed seafood gumbo. One of the above posts said that either file or okra is used but not both. I have eaten it with both and usually cook it that way. Want a recipe for "Dirty Rice"?
