For anyone looking to make a real deep south gumbo. I live on the coast of Mississippi so when I say deep south, there isn't much further south you can go outside of Florida (which traditionally is not known for its southern cooking).
Don't get up caught up if you don't have the exact ingredients, as gumbo was a dish invented out of necessity. The idea of a gumbo is to cook whatever you have around, maybe that's about to go bad, with a dark reaux (thick broth). It was a dish prepared by the poor for the poor. Ironically, by using a set list of ingredients, it actually ends up costing a good bit (especially with a seafood gumbo). Don't have tomato paste or okra.... whatever. Can't find andouille sausage, big deal, use hickory smoked. Point is to just go with it.
2 cups canola, vegetable oil or butter. 2 cups flour.
1 pack andouille sausage
1 small can of tomato paste or sauce
Onion, bellpepper, celery, bag of frozen okra, garlic to taste, bay leaf
Seafood such as shrimp (prawn) and crab. You can also use boiled chicken or egg if you are strapped for cash.
Liquid or powdered crab boil
Salt, pepper, Cajun seasoning, basil to taste
The hardest part is getting the reaux right. Get yourself a deep pan hot at medium and then add oil. Slowly sift flour in while continuously stirring. When I say continuously, I mean continuously. You gonna watch for smoke and adjust temperature accordingly. A little smoke is expected, but you do not want to burn the flour as you will have to start again. This can take up to 30 minutes.
Continue this process until the reaux because a dark color similiar to milk chocolate. Take off heat and let cool for 10 minutes before adding 2 quarts of water or chicken broth and tablespoon of crab boil. Throw in a bay leaf or two and turn on heat back to medium. Your reaux and water/broth will be separated at first, no worries as it will work together as it cooks and you stir.
At this point slice your sausage and brown. Remove sausage but leave grease as you are now going to throw in the onion, bellpepper, and celery. Throw some garlic in at the end and turn off heat. Stir for 30 seconds and throw in the pot with reaux and water. Add sausage as well.
Open up your can of tomato paste/sauce and scope out a heaping tablespoon. Stir this into your broth.
Bring to boil and reduce heat to low. If using chicken, this is the time to add it. Cook for at least an hour. Afterwards taste and add your seasonings. There is no right or wrong here, add to taste. Make it spicy with cayenne if you would like.
Take your okra and throw in a pot and cook until slime is mostly gone and the okra is tender. This can be a pain in the ass.
If using seafood or egg, add now along with okra and cook on low for another hour.
It's ready to go now but there is nothing wrong with letting it cook down, I tend to let it go for up to 4 hours. Put some rice in the bowl and pour your gumbo over top.
