Yambo

Gumbo is a stew that is popular in the U.S. state of Louisiana and is the official state cuisine. Gumbo consists primarily of a strongly flavored stock, meat or shellfish (or sometimes both), a thickener, and the Creole "holy trinity" – celery, bell peppers, and onions. Gumbo is often categorized by the type of thickener used, whether okra or filé powder (dried and ground sassafras leaves). Gumbo can be made with or without okra or filé powder. The preferred method in the historical New Orleans variation is with a French dark, even chocolate-like, roux. The flavor of the dish has its origins in many cultures. Creole gumbo generally contains shellfish and a dark roux, filé, or both. Cajun gumbo is generally based on a dark roux and is made with shellfish or fowl. Sausage or ham is often added to gumbos of either variety. After the base is prepared, vegetables are cooked down, and then meat is added. The dish simmers for a minimum of three hours, with shellfish and some spices added near the end. If desired, filé powder is added after the pot is removed from heat. Gumbo is traditionally served with rice. A third, lesser-known variety, the meatless gumbo z'herbes, is essentially a gumbo of slow-cooked greens.
