Bicerin is a coffee specialty from Torino. The exact mixture is, like the Viennese Sachertorte, a secret of the Café "Al Bicerin" which was founded in 1763. Generally, Bicerin is a mixture of espresso and hot chocolate, topped with "crema di latte" which is something like creme double. Don't use steamed milk! If you don't have creme double or heavy cream, use whipping cream which is just lightly whipped, not stiff.
