The critical factor in making this gumbo is time. Take your time making the roux, and take your time cooking the gumbo. It might take 4 hours for some tough cuts to submit. Just drink a few beers and relax; it'll all come out well in the end. If you are not a hunter, your cooking time will be less. I would suggest the following combination: venison shoulder, shank or neck, some turkey legs, a ham hock, and smoked andouille sausage.
2green onions and 1-2 tablespoons chopped parsley per person
Bring the stock to a gentle simmer.
In a Dutch oven or large pot, add the cup of oil to the pot, and turn the heat to medium-high. Whisk in the flour, and stir this frequently until it turns the color of chocolate. You can go as dark as dark chocolate brown, but under no circumstances can you let this roux burn. Keep in mind that this takes time, maybe 15 to 25 minutes of frequent stirring.
When the roux is ready, add the peppers, onions, celery and garlic and stir to combine. Cook this, stirring often, for 6 to 8 minutes, until the veggies are soft.
Meanwhile, mix all the dry spices together except the filé powder.
When the veggies are soft, ladle in the stock with one hand while stirring with the other. Stir in each ladle of stock before adding another. Turn the heat to high to bring the gumbo to a strong simmer.
Add half the spices, stir to combine, and add the meats except the sausage, if using. Taste and add more salt or spices if you want. Drop the heat to a simmer, cover and cook gently for at least 90 minutes, but probably more like 2 to 3 hours. Check the status of the meats every half-hour after 90 minutes have elapsed. When the meats are about falling off the bone, fish them out and when they cool enough to handle them, pick the meat off the bones. Return the meats to the gumbo and add the andouille. Cook for another 15 minutes or so.
Add the filé powder, the green onions and parsley. Cook for 3 minutes more. Serve with rice or all by itself.
You will want to get some filé powder, which is powdered sassafrass. It is an important flavor component here, and the filé (FEE-lay) needs to be added at the end of the process. If you cannot find it, do without. But be sure to look at least before you omit.
