Nutella® the most well-known brand of chocolate hazelnut spread, in its earliest form, was created in the 1940s by Mr. Pietro Ferrero, a pastry maker and founder of the Ferrero company. At the time, there was very little chocolate because cocoa was in short supply due to World War II rationing. Mr. Ferrero used hazelnuts, which are plentiful in the Piedmont region of Italy (northwest), to extend the chocolate supply. New 3 KG jar. Original Italian recipe.
