Hot chocolate

Hot chocolate (or hot cocoa) is an Earth drink typically made by mixing cocoa powder in boiling hot milk. Deanna Troi was a fan of hot chocolate, no doubt an extension of her love of chocolate. 

In 2365, Ensign Sonya Gomez ordered hot chocolate from a replicator in main engineering and later spilled it on Captain Picard. 

In 2370, on the day after the fourth anniversary of Jennifer's death at Wolf 359, Benjamin Sisko suggested to Jake that he get a hot chocolate and talk to him about his mother.
