Blackened redfish

From Memory Alpha, the free Star Trek reference.

Blackened redfish is a Creole dish. It was once prepared and served at a banquet by Benjamin Sisko for his senior staff. Sisko, as with many recipes, learned this one from his father's restaurant in New Orleans. (DS9: "Equilibrium")

In an alternate timeline, Jake Sisko and his wife Korena enjoyed blackened redfish. (DS9: "The Visitor")
