Flush the wound surface and interior as you can with a mild solution. A saline solution made from a small amount of salt diluted in water works well since it mimics your bodyâs internal pH. You can also use mild or diluted soap in water works well or some purified water, then wipe the surface with clean gauze.
Stock to roux ratios in gumbo vary from about 20-1 (soupy) to about 6-1 (stew). Using a 10-1 ratio, I'd say about 6 1/2 cups of flour for the roux. 15 pounds of meat. 4 gallons stock. 5 1/3 pounds rice. That should make about 40 16oz servings.
5 While you are stirring and cooking the roux, bring the chicken stock and water to a boil in a separate pot. 6 Add to the roux the onion, green pepper and celery and mix well. Let this cook, stirring often, for about 5 minutes. Add the garlic, stir again and cook for another 2 minutes. Mix in the tomato paste. 7 Using a large ladle, add the hot chicken stock to the gumbo.
