A milaberry is a fruit found on Bajor.
In 2347, Ro Laren thought that the candy given to her by a Cardassian while on her way to see her father Ro Gale tortured was as sweet as milaberries. (TNG short story: "Flash Point")
In 2375, Winn Adami and Dukat (disguised as Anjohl Tennan) ate milaberries in their guest quarters on Deep Space 9. (DS9 episode: "Strange Bedfellows")
