This might not be true Cajun but it is quite good! The best gumbo needs time to cook, so make this recipe when you have some time, it will take just over 3 hours to make, that is including boiling the chicken. Although it is pretty hard to improve on this gumbo, please don't omit the browning your sausage step firstly, it will bring out more flavor to the gumbo! if possible use andouille sausage for this if not any good-quality dry smoked sausage will do fine! The black beans are optional, I most always add them in! If you like extreme heat then add in cayenne or red pepper to taste. Don't let the amount of oil scare you, it will rise to the top when the gumbo is cooking and will be skimmed it off the top. Serve the gumbo over hot cooked rice.
