This festive holiday drink is served with a peppermint stick.
Place cocoa in a medium saucepan. Gradually whisk in milk until cocoa has dissolved. Add chocolate chips and crushed peppermint; simmer over medium heat, stirring occasionally, until chocolate and peppermint have melted, 8 to 10 minutes.
Bring to a boil and immediately remove from heat. Add salt. Ladle into mugs; serve each with a peppermint stick.
