Not a true Cajun recipe at all! I am a Cajun from Louisiana and this is not authentic. We do NOT put clam chowder, nor do we put tomato anything in our gumbos.
OKay, cajuns do not: even eat clam chowder use tomatoes in their gumbo use okra in their gumbo don't use fish in their gumbo!! From a Louisianaian, I must say this isn't even close to gumbo.
