OK - There are two ways to make gumbo. The usual way takes a good bit of time, but tastes far better. The "Lazy man's gumbo" is much quicker, doesn't taste nearly as good, but is equally effective against gout.
Traditional Shrimp (NOT "seafood") gumbo:
First, you make a roux... Look on the internet for a dozen ways to make roux, and decide which tastes best to you.
Chop between one and three onions (depending on how big a gumbo you're making)
Chop bell peppers and garlic cloves (about half the volume of your onions)
Get (low sodium) chicken stock proportional to the amount of roux you make
Between two and four pounds of shrimp (get Gulf or pond-farmed shrimp if you can - nothing from Thailand, Vietnam, or India, etc.)
If you're weird, you can add okra, tomatoes, celery, etc.
After you brown your roux, dilute with water or chicken stock until the roux & diluent are thoroughly mixed & boiling.
Brown all your vegetables, and add them to the mix.
Reduce to a simmer and cook for about 30 minutes to an hour.
Add your shrimp and simmer for at least two hours.
Serve as a soup or on rice with chopped green onions & gumbo filé.
Lazy man's gumbo:
Buy a jar of roux & follow the instructions on the jar for blending it into (low sodium) chicken stock.
Buy a BIG bag or two of "frozen seasoning mix" and wash it to remove the rime ice.
Dump the seasoning mix into the roux/chicken stock mixture and simmer for at least a half-hour.
Add enough shrimp so that every spoonful will have at least one shrimp in it.
Simmer for no more than about an hour to an hour and a half.
Serve on rice (or as a soup) with chopped green onions & gumbo filé.
Now
novisnick (a restaurant owner and GREAT chef) will blanche at both of these "recipes," but my goal here isn't to serve gourmet gumbo, but to control gout. If you're a picky eater, feel free to make a better quality gumbo, but for my purposes, either of the above are equally effective.
NOTE: ALL gumbo tastes better on the second day (the flavors have more time to mix). I normally freeze half (or more) of each gumbo batch I make and a big pot will last me about a week.
