This is a stew-like dish commonly served over rice consisting of vegetables and a variety of ingredients such as shrimp, crab, crawfish, oysters, rabbit, chicken or andouille. It may or may not be spicy. Gumbo was brought to the American south by African slaves. The word 'gumbo' is the African word for okra, the African vegetabled used to thicken gumbo. Gumbo may also be thickened by Filé Powder, ground sassafras leaves to create what is reffered to as Filé Gumbo. The French adapted the original form of gumbo, with a roux, which later became the present day form of gumbo as we know it.
