I need a good chicken and sausage gumbo receipe using a Zatarain's gumbo mix. They sell a package of mix with rice already in it. I like to make my own rice. I have used Zatarain's mix but they also have a dry roux mix. With the box of gumbo mix you just add water and your meat. I wonder how much of the roux mix it takes to make say 5 quarts. Thanks.
