Replicated black hole
A black hole is a somewhat repulsive Ferengi drink that Jadzia Dax enjoyed having for breakfast. Dax was introduced to the black hole by a bartender she has known for 100 years. (DS9: "The Circle", "Playing God")
When Rom became a technician on Deep Space 9 in 2372, he told Quark that he had wiped his last table and mixed his last black hole. (DS9: "Bar Association")
The drink was ordered by another customer later that year. (DS9: "Hard Time")
