An elaborate dessert containing seventeen varieties of chocolate, which Deanna Troi introduces to the pleasure-seeking Iyaaran ambassador Loquel in the episode Liaisons.
The Ktarian chocolate puff is a dessert served in Ten Forward, seen in The Next Generation episode Liaisons, set in 2370.
Two Iyaaran ambassadors come aboard the Enterprise-D as part of a cultural exchange, each secretly assigned to study a single human experience. Loquel, attached to Counsellor Troi, has been sent to learn about pleasure, a concept unknown to his people, who feed on bland nutrients. Troi shows him the dessert menu and recommends the Ktarian chocolate puff, explaining that it is made with seventeen kinds of chocolate.
Loquel is overwhelmed and spends the rest of the visit eating his way through every sweet on the ship. His colleague Byleth, meanwhile, studies antagonism by provoking Worf.
