RECIPE FOR NUTRIA SAUCE PICANTE
Prepare the nutria meat. Thoroughly cover the meat with tenderizer and Cajun seasoning (Tony Chachere's is the best) overnight for best results. If pressed for time, cover meat with tenderizer and Cajun seasoning, and let sit for at least 1/2 hour. Cut meat into bite-sized pieces for best flavor. Use 3 to 4 pounds of meat for the following sauce recipe. If the hungry-man's portion is desired, use 5 pounds.
On low heat, in large pasta pot or good-sized heavy pan, slowly cook seasoned meat in 1 pound of real butter (with salt) until golden brown (about 20 minutes). Add 1 cup of chopped onions, 1 cup of chopped shallots, 1 cup of diced green bell peppers, 1 cup of diced celery, 1 teaspoon of salt, 1 teaspoon of A-1 Sauce and 1 teaspoon of white pepper. Continue to heat on low, cooking for an additional 20 minutes.
Turn heat up to medium temperature, add 2 large cans of Ro-Tel diced green chilies and tomatoes - use medium or hot flavors to suit taste. Stir constantly for 10 more minutes to avoid burning the meat or the butter. Add 1 package of instant brown gravy. Only add the package contents. Do not add water as the package instructions indicate for making actual gravy. Tony's also sells a pre-made dark roux in a jar. If using this, add 1 Tablespoon of Tony's Dark Brown Roux. Turn heat to simmer. Add 2 large cans of your favorite tomato sauce (Prego, Ragu, Hunt's, etc.). My best results have been with Hunt's canned sauce -- use the garlic-and-herb-flavored sauce. Allow to simmer for 30 minutes. If sauce becomes thick, thin with small amounts (1/2 cup or less) of water. Taste for salt & pepper seasoning, and adjust according to taste.
For a traditional Cajun dish, serve sauce in large bowl with an ice cream scoop of rice in the middle. For a traditional American dish, serve sauce in large bowl poured over pasta or egg noodles.
