Gianduia or gianduja (Italian: [dʒanˈduːja]; Piedmontese:
giandoja [dʒaŋˈdʊja]) is a homogeneous blend of
chocolate
with 30% hazelnut paste, invented in Turin during Napoleon's regency (1796–1814). It can be consumed in the
form of bars
or as a filling for chocolates. Chocolate spreads are also notably made from gianduja.
Gianduja is made in both plain and milk versions. It may also contain other nuts, such as almond. As a
bar, gianduja
resembles regular chocolate, excepting the fact that it is significantly softer due to the presence of
hazelnut oil.
