I too like my cocoa unsweetened and made with good quality cocoa. During my many visits to Italy I have drank many hot chocolates in bars and each one I ordered was different in taste and thickness.
As a child living in Trieste, I grew up with drinking hot chocolate. It was my breakfast, it was drunk at childrens’ parties and at bars while the adults drank coffee. Trieste is close to Austria and the hot chocolate I was used to was always presented in a fine tea cup with a blob of whipped cream. It was always made with a generous quantity of quality cocoa powder and with milk. My mother always made it in a pentolino (we had a special small saucepan that we only used for heating milk) and she would stir the mixture until hot. When in bars the same ingredients were used, but the milk was foamed like in a cappuccino or caffé latte.
When my family travelled to Sicily (each summer), my relatives gave me milk with a dash of coffee for breakfast – hot chocolate did not seem very popular and I remember the hot chocolate in bars being rather watery and very sweet.
I tasted my first, thick hot chocolate when I first went to Mantova. It was almost the consistency of custard. Those of you who have ordered hot chocolate anywhere north of Rome (except Trieste) would know what I am talking about – milk, sugar, thickening (usually corn flour or potato starch), and chocolate (often cocoa powder). No thickening seems to be used anywhere south of Rome.
Traditionally, thick chocolate was made in the top of a double boiler, over boiling water – good quality, dark chocolate (not cocoa) is melted in water and stirred until it is dissolved. Still over heat, it is then whisked by hand for at least 3 minutes (in a modern kitchen, an electric wand can be used).
Another recipe for making a good tasting, thick, hot chocolate also contains some shaved good quality bittersweet chocolate (high level cocoa-70-80%) as well as the good quality cocoa, milk and sugar to taste (Italians like sugar). In a milk saucepan, mix the sugar and cocoa with a little bit of milk till smooth. Add milk and stir over medium heat. Add the bits of chocolate to taste (and preferred thickness). Keep on stirring till melted.
It can be an alternative to dessert.
