   1      cup           vegetable oil
   3      quarts        crawfish stock or water
   1      cup           flour
   1      cup           chopped green onions
   2      cups          chopped onions
   1      cup           chopped parsley
   1      cup           chopped celery
                        salt and cayenne pepper to taste

   1      dash          Louisiana gold pepper sauce
   2      tablespoons   diced garlic

Preparation:

A rich crawfish stock will certainly make this dish a winner. Any shellfish stock or fish stock may be substituted, but the dish will be good even if plain water is used. In a two gallon stock pot, heat oil over medium high heat. Add flour and using a wire whip, stir constantly until dark brown roux is achieved. When brown, add onions, celery, bell pepper and garlic and Sauté until vegetables are wilted, approximately three to five minutes. Add crawfish tails and cook until meat is pink and slightly curled. Stir in tomato sauce and slowly add crawfish stock stirring constantly until all is incorporated. Bring to a low boil, reduce to simmer and cook thirty minutes, stirring occasionally. Add green onions and parsley and season to taste using salt and pepper. When done, serve over white rice with a few dashes of Louisiana Gold Pepper Sauce. Source: Chef John Folse
