What Is Gianduia?

If you've had Nutella or Ferrero Rocher before, you probably didn't realize there's a name behind that iconic flavor of chocolate and hazelnut. That name is gianduia, pronounced jan-DOO-yah. It's one of the most comforting and classic combinations in Italian confectionery.

But gianduia wasn't invented as a luxury. It was invented out of necessity.

How it got its name

The word gianduia actually predates chocolate entirely. It originally belonged to a beloved character from Commedia dell'Arte, traditional Italian theater, an honest, good-natured peasant from the Piedmontese countryside, recognizable by his tricorn hat and brown jacket trimmed in red. He's still considered Turin's official Carnival mask to this day. And if you have ever traveled to Turin, you'll notice the gianduiotti chocolates are shaped like small boats, or elongated triangular wedges, and that shape is directly representative of his tricorn hat.

Born from a blockade

In the early 1800s, Napoleon enforced what became known as the Continental Blockade, which cut off much of Europe from British trade, and with it, the flow of South American cocoa. Turin, a city already known for serious chocolate making, suddenly found its cocoa supply running low with no easy way to restock. Rather than lower the quality of their chocolate or stop production entirely, Turin's chocolatiers turned to what was actually plentiful nearby, hazelnuts from the Langhe hills, specifically the prized Tonda Gentile variety. By stretching their limited cocoa with finely ground hazelnuts, they created something smoother and more aromatic than either ingredient alone, and it was named gianduia after that same beloved Carnival character.

What started as a practical solution to a cocoa shortage became one of the most beloved flavor combinations in Italian history. You can taste its influence everywhere now, in gianduiotti, in Baci di Dama, the little hazelnut kiss cookies sandwiched together with chocolate, and yes, in Nutella and Ferrero Rocher too, both of which trace their flavor logic directly back to this same Turin tradition.

Bringing it into gelato

For my own gianduia gelato, which you'll find in my upcoming cookbook, I roast Piedmontese hazelnuts and cocoa nibs myself and grind them into paste, staying close to the authentic, traditional way of making gianduia and showing how simple it is to make at home, but so rewarding.

The hazelnuts specifically come from the same Langhe hills tied to the story, the Tonda Gentile Trilobata variety, which carries PGI protection in Italy, meaning only hazelnuts genuinely grown in that specific region can legally carry the name. It's the same reasoning behind why Parmigiano Reggiano can only come from certain provinces, the land itself is part of what makes the ingredient what it is. In fact, EU regulation actually defines what can legally be called gianduia, requiring hazelnuts to make up between 20 and 40 percent of the product by weight.

No shortcuts, no fillers, just real hazelnuts and real cocoa cooked directly into the base. Knowing the story and the place behind it makes the flavor feel even more worth getting exactly right.
