This is a gumbo made without a roux - I had to learn how to make this for my first hubby because that's how his mom made it! It took me a few tries to get it to brown enough, but, once I learned the secret (a good, heavy pot!) my gumbo by far surpassed hers. If you use wild goose you have to let it simmer a long time (2 to 4 hours) and keep the liquid level up. Ducks, depending on size, will get tender in 1 to 2 hours It's some trouble, but worth the effort.
