Italian chocolate: gianduja, Turin and thick hot chocolate
A hazelnut tradition born of a cocoa shortage, and a drinking chocolate thick enough to stand a spoon in.
If you read nothing else
Hazelnut chocolate is Italy's contribution and it began as a way of stretching scarce cocoa. Treat gianduja as a filling, not as a coating — it will not set.
Hazelnut is the signature, and it started as a substitution
Blockade conditions in the Napoleonic period restricted cocoa into continental Europe. Piedmont had hazelnuts, and grinding them into the available cocoa made it go further. The result — gianduja — outlived the shortage because it turned out to be desirable in its own right.
The gianduiotto, an ingot-shaped moulded piece, is the Turin form. The global descendant is the industrial hazelnut spread, which is one of the most widely eaten chocolate products in the world and comes from the same substitution.
Gianduja does not behave like chocolate
Hazelnut oil is liquid at room temperature, so gianduja is softer, melts faster and has almost no snap. It cannot be substituted for couverture: it will not temper conventionally and a recipe relying on it to set will not set.
Use it where softness is the intention — as a filling, a spread, a layer — and not as a coating.
Cioccolata calda and bicerin
Italian hot chocolate is thickened, usually with starch, and served in small volumes with a spoon. It is a different drink from a northern European hot chocolate rather than a stronger one.
Turin's bicerin layers coffee, chocolate and milk in a small glass without stirring, and is old enough to be an institution. Both are café products made to house recipes rather than to a standard.
