1 (5 pound) roasting chicken , cut up
Salt
Cayenne pepper
Garlic powder
2 1/2 cups all-purpose flour
1 cup vegetable oil
2 cups onions, coarsely chopped
1 1/2 cups celery, coarsely chopped
2 cups green bell pepper, coarsely chopped
6 cups chicken broth
1 1/2 teaspoons fresh garlic, minced
1 pound andouille sausage finely, diced (or a
    spicy sausage such as Kielbasa)
4 cups hot cooked rice

Cut chicken breasts in half crosswise to get a total of 10 pieces of chicken. Season with salt, cayenne pepper and garlic powder and let stand at room temperature for 30 minutes. Measure flour into a large paper bag. Add chicken pieces and shake until well-coated. Remove chicken and reserve the flour.

In a large cast iron skillet, brown chicken in very hot oil, remove and set aside. Stir oil remaining in the skillet with a wire whisk to loosen any brown particles remaining in the bottom of the pan. Whisk in 1 cup of the remaining flour and stir constantly until the mixture of oil and flour (the roux) becomes dark brown (do not burn!). Remove from heat; add onions, celery and green bell pepper, stirring constantly until vegetables are tender.

Transfer roux and vegetables to a large heavy saucepan. Add stock to roux and vegetables and bring to a boil, stirring. Lower heat to a quick simmer and add garlic, sausage and chicken. Continue cooking, covered, until the chicken is tender, 1 3/4 to 2 hours. Adjust seasonings and serve in bowls over the rice.
