Hot Chocolate for Adults Only 1/2 cup chocolate chips 3 cups milk 1 cup half-and-half 1/2 cup granulated sugar 1/2 cup rum 1/2 cup almond or hazelnut liqueur Whipped cream and cinnamon sticks Melt chocolate chips over simmering water. Combine milk, half-and-half and sugar in a saucepan and bring to a simmer (so that bubbles are just beginning to form around the edge of the pan). Very slowly add about 1 cup of the milk mixture to the melted chocolate and mix thoroughly. Pour chocolate mixture back into remaining milk mixture. Stir in rum and liqueur. Pour into mugs and top with a dollop of whipped cream and a cinnamon stick. Serve at once.
