Ferrero Rocher is a chocolate and hazelnut confectionery produced by the Italian chocolatier Ferrero SpA.
The Ferrero Rocher was introduced in 1982 in Europe. Shortly after release, production was halted due to a problem with label printing. Michele Ferrero, the credited inventor, named the chocolate after a grotto in the Roman Catholic shrine of Lourdes. Rocher comes from the French and means rock or boulder.
The chocolate consisted of a whole roasted hazelnut (but since late 2017, only part of a hazelnut had been used) encased in a thin wafer shell filled with hazelnut chocolate and covered in milk chocolate and chopped hazelnuts. Its ingredients are milk chocolate, sugar, cocoa butter, cocoa mass, skim milk powder, butter-oil, lecithin as emulsifier (soy), vanillin (artificial flavor), hazelnuts, palm oil, wheat flour, whey (milk), low-fat cocoa powder, sodium bicarbonate (leavening agent), and salt.
