Gumbo is a hearty, spicy Earth stew that was served at Sisko's in New Orleans.
Joseph Sisko had a secret gumbo recipe that he planned to take with him to the grave. (DS9: "Image in the Sand")
Sisko had his chef Nathan prepare some gumbo for his son and grandson upon their arrival in 2372; Benjamin later remarked the gumbo was as good as ever. (DS9: "Homefront")
