Ever had Nutella?

It's good, isn't it? What if I told you its origins were serendipitous?

During the war, ingredients needed to make chocolate were in short supply, so ... Pietro Ferrero began experimenting by mixing in hazelnuts to increase the volume, according to the company’s Web site. From this came Nutella, the chocolate-hazelnut spread that has been produced since the early 1960s and has been available in the United States since 1983.
