If you cook to fast, it will burn easy. Once it is to the correct color and the tomato paste has been added, then add the yellow onions and bell pepper. Cook for about 2 minutes in the roux then add the chicken and garlic and cook another 2 minutes. Be sure to continually stir at this point. You can also add sausage now if you want, but be sure it is heavily smoked. Now is the time to add the water, salt, pepper, cayenne, green onion, and parsley. Bring to a slow boil and simmer for about 1 hour stirring occasionally. Serve over Aromatic Rice like a soup and a large scoop of rice in the middle of the bowl. ENJOY because it the real thing without going to Louisiana. You can make this Sauce Picante with Shrimp, and Turtle as the meat also. Use as much meat as you like.
