Gumbo is a popular stew, especially along the U.S. Gulf Coast. The New Orleans variation holds the distinction of being Louisiana's official state cuisine. Key ingredients include a flavorful stock, meat or shellfish, and a thickener, along with the "holy trinity" of Creole cooking: celery, bell peppers, and onions. Gumbo variations are often classified by the thickener used, primarily okra or filé powder.
Following the death of Senator Allen Ellender in 1972, the U.S. Senate added Louisiana Creole Gumbo to its cafeteria menu as a tribute. This marked a turning point in the popularity of gumbo, expanding its reach beyond the Gulf Coast.
