The gianduiotto is chocolate originally from Piedmont, in northern Italy; they are shaped as ingots. Gianduiotti are individually wrapped in a (usually) gold- or silver-coloured foil cover. It is a specialty of Turin, and takes its name from gianduja, the preparation of chocolate and hazelnut used for gianduiotti and other sweets. This preparation itself is named after Gianduja, a mask in commedia dell'arte, a type of Italian theater, that represents the archetypal Piedmontese. Indeed, Gianduja's hat inspired the shape of the gianduiotto.
