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.
Classic gumbo recipes call for okra simmered for hours in a roux, a dark stock made from either butter or oil and flour, with a variety of meats, onions, celery and bell peppers. Served over rice, variations include seafood gumbo with shrimp, oysters and crabmeat or chicken gumbo with andouille sausage.
