A rich dessert made with cocoa beans from Thalos VII, which Wesley Crusher orders from the replicator for the young ruler Salia in The Dauphin.
Thalian chocolate mousse is a dessert seen in The Next Generation episode The Dauphin, set in 2365.
Wesley Crusher, smitten with Salia, the sixteen-year-old future ruler of Daled IV, invites her to see something of the ship. He asks the replicator for Thalian chocolate mousse and explains that it is made from a cocoa bean grown on Thalos VII and aged for four hundred years. Salia has never tasted anything like it and is delighted.
The mousse is part of Wesley's attempt to show her the wider galaxy before duty claims her. Her guardian Anya, a fellow shapeshifter, takes a much dimmer view of the friendship, and the two teenagers part when Salia beams down to her world.
