Gianduja
Chocolate blended with roasted hazelnut paste, from Piedmont. The origin of the entire chocolate-hazelnut category, invented because cacao was scarce.
What it is
Gianduja is chocolate combined with finely ground roasted hazelnuts, traditionally at a substantial proportion — enough that the nut is a component rather than a flavouring. It comes from Turin, and the usual account is that it was developed during a period when cacao supply was restricted and hazelnuts, which Piedmont has in quantity, were used to extend it.
The nut fat changes the physics. Hazelnut oil is liquid at room temperature, so gianduja is softer than chocolate, melts at a lower temperature, and cannot hold a snap. That is why it is used for spreads, fillings and soft moulded pieces rather than for bars that need to survive a warm room.

What the percentage means here
Total cacao-derived mass, which on gianduja is diluted by the hazelnut fraction rather than only by sugar. A 32% gianduja is not comparable to a 32% milk chocolate: a substantial part of its remaining mass is nut.
Legal minimums
These differ by jurisdiction, and the difference is real rather than technical: the same words on a wrapper describe different products either side of the Atlantic.
| Jurisdiction | Component | Minimum | Instrument |
|---|---|---|---|
| European Union | total dry cocoa solids | 32% | Directive 2000/36/EC |
- European Union: The EU instrument defines gianduja and gianduja milk chocolate separately, specifying both a cocoa floor and a permitted range for the hazelnut content — one of the few nut-containing products with its own standard.
Working with it
Softer than chocolate and lower-melting, because hazelnut oil is liquid at room temperature. It will not temper to a hard snap and should not be used where a moulded shell needs to hold its shape unsupported.
Commonly misunderstood
That it is chocolate with hazelnut flavouring added. The nut is ground into the mass as a major component, which is why it behaves so differently from a flavoured chocolate.

Techniques that work with this
- Making pralinéNuts caramelised in sugar and ground to a paste. The caramelisation is the flavour and the grinding is the work.
- Italian hot chocolateThickened, served in small volumes, and finished with cream on top rather than stirred through — a café product rather than a mug of cocoa.
