Aubergine stew was a Persian dish from Earth that included aubergine (a type of eggplant) and the meat of young sheep. The dish was one of Benjamin Sisko's specialties, and was well known among those close to him.
Sisko also made this stew for dinner for himself and his son in 2369 but Jake did not show up. When Jadzia Dax came along she seemed happy about this meal and ate it when Sisko left to search for Jake. (DS9: "The Nagus")
