Ferrero Rocher is a spherical chocolate sweet introduced by Italian chocolatier Ferrero SpA. Introduced in 1982, the chocolates consist of a whole roasted hazelnut encased in a thin wafer shell filled with hazelnut cream including vegetable oil and covered in milk chocolate and chopped hazelnuts.[1] The sweets each contain 73 calories and are individually packaged inside a gold-coloured wrapper. Rocher comes from French and means "rock", after a grotto in the Roman Catholic shrine of Lourdes, reflecting Michele Ferrero's devout faith.[2] It could also be named after Michele Ferrero's mother, Piera Rocher. Ferrero SpA is also known for its Nutella, Kinder Surprise and Tic Tac products.[3]
