When Quark had apparently repaired his replicators in 2369, he convinced Jadzia Dax to eat a double-whipped I'danian spice pudding, which unfortunately infected her with the aphasia virus. (DS9: "Babel")
In 2370, after he had nearly died, Elim Garak simply asked Bashir how the I'danian spice pudding was today. (DS9: "The Wire")
In 2371, when Jake Sisko was on Earth, he made an attempt at finding a decent bowl of this pudding on Earth. He tried several replicators without success. Upon arriving home at Deep Space 9, he ordered a bowl of this pudding. (DS9: "The Search, Part I")
Later that year, Quark also served the pudding at the party given by Commander Sisko during the Bajoran Gratitude Festival. (DS9: "Fascination")
