Gianduiotto is Turin's gift to the chocolate world—a small, boat-shaped (or inverted-triangle) chocolate confection made from gianduja paste, the distinctive Piedmontese blend of chocolate and roasted Tonda Gentile hazelnuts that was invented in Turin in the early 19th century as a response to Napoleon's Continental Blockade, which restricted the import of cacao from the Americas. Ingenious Torinese chocolatiers extended their limited cacao supply by blending it with the abundant, high-quality hazelnuts of the Langhe hills (Nocciola Tonda Gentile delle Langhe IGP), creating a new confection that was not merely a compromise but a genuine improvement—the hazelnut's fat content produces an extraordinarily smooth, melt-in-the-mouth texture, while its nutty sweetness harmonizes with the chocolate's bitterness in a way that neither ingredient achieves alone. The gianduiotto is formed by machine or by hand into its characteristic shape, individually wrapped in gold or silver foil, and has been Turin's signature confection since 1865, when the chocolatier Caffarel first distributed them during the Turin Carnival. The chocolate-hazelnut ratio in genuine gianduja is roughly 60% chocolate to 40% hazelnut paste, though each manufacturer guards their precise formula. The hazelnuts must be Tonda Gentile—their exceptionally round shape, high oil content, and clean flavour are irreplaceable; substituting other hazelnut varieties produces an inferior product. Modern descendants of the gianduja tradition include Nutella (created by Ferrero in Alba in 1964) and the premium gianduja bars and spreads produced by artisan chocolatiers in Turin. The city's great cioccolaterie—Baratti & Milano, Peyrano, Guido Gobino, Strata—maintain the artisan tradition, producing gianduiotti of exquisite quality that bear no resemblance to industrial versions.
Blend of chocolate and roasted Tonda Gentile hazelnut paste. Roughly 60/40 chocolate to hazelnut ratio. Characteristic boat or triangle shape. Individually foil-wrapped. Use only Tonda Gentile delle Langhe hazelnuts.
Toast the hazelnuts until the skins crack and rub off—the Maillard reaction develops deeper flavour. Grind hazelnuts until they release their oil and form a smooth paste before combining with chocolate. Genuine gianduja should melt on the tongue with no grit. Visit Turin's cioccolaterie during the November CioccolaTò festival.
Using generic hazelnuts (wrong flavour and texture). Too much sugar (should taste of chocolate and hazelnut, not sweetness). Insufficient hazelnut content. Confusing with mass-produced 'gianduja' products.
