Filé gumbo

Gumbo is a stew that is popular among the U.S. Gulf Coast community, the New Orleans stew variation being the official state cuisine of the U.S. state of Louisiana. 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).
