An empty Q'parol dish
Q'parol was a type of casserole dish, described as very time-consuming to prepare.
A Pah-wraith possessing Keiko O'Brien prepared Q'parol for Miles O'Brien's birthday in 2373, which Captain Sisko rated very high. Jadzia Dax arrived late to the party, yet explained that she knew she couldn't miss it after hearing Keiko would be preparing the dish. After the party was over, Keiko held up the empty dish and claimed that it "was a big success". (DS9: "The Assignment")
