Being married to a Louisiana man has many perks. His bone fide gumbo is one of them. Oliver used the carcass from last week's roast chicken, and several chicken backs from the freezer, to create a foundation stock for the soup. He then made a roux and added the food "trinity" (onions, bell peppers and celery). Once everything had cooked down it was combined with the stock, a freshly browned chicken and some andouille. The gumbo was left to simmer for a couple of hours in our cast iron pot.
