File' Powder
Filé(file powder), or as it is also known because of its association with gumbo, gumbo filé, is the powdered dried leaves of the sassafras tree. The Choctaw Indians (Mississippi and Alabama) first used this seasoning. It has a flavor resembling that of root beer. It is an essential flavoring and thickening ingredient of gumbo and other Créole dishes. Filé is generally added after cooking, when the dish has been removed from the heat, but still hot, because it becomes stringy with cooking.
