Ktarian chocolate puff

From Memory Alpha, the free Star Trek reference

Ktarian chocolate puff is a large dome-shaped dessert originating from the Ktarians. It is made from 17 varieties of chocolate and is one of Deanna Troi's favorite confections. It was served at a reception held aboard the USS Enterprise-D in 2370 for a visiting Iyaaran delegation. (TNG: "Liaisons")

In 2377, the Doctor, while possessing Seven of Nine's body, ate three servings of Ktarian chocolate puff while dining with Ranek, the captain of a Lokirrim vessel who had taken them captive. (VOY: "Body and Soul")
