Joe Dizney learned how to make gumbo from watching his grandmother cook batches of it in her 1950s Louisiana kitchen. Now he makes it out of his own kitchen on special occasions (or whenever he has a poultry carcass lying around) using the same, well-worn cast iron skillet his grandmother used. In this episode, Joe shows Jennifer how to make a proper Cajun roux and how to temper it before adding it to the simmering stock (to minimize its “Cajun napalm” quality), which Joe seasons with his own blend of “leaves and seeds.” Jennifer also learns a thing or two about sassafrass leaves, okra, and the trinity of black, white, and red pepper.
