A History of Chocolate and Hazelnuts

These days, chocolate and hazelnuts bring to mind the ubiquitous (and sugar-filled) spread, Nutella but the pairing is far older than that. This fabulous flavor marriage began in Turin, a city in northern Italy, in the early 1800s.

This was at a time when cocoa was both expensive and difficult to import so chocolate was hard to get. Turin was in an area where hazelnuts grew in abundance and someone had the idea to swap out some of the cocoa for hazelnuts to make chocolate more affordable to prepare and purchase. The result was called gianduia, and it was eventually turned into a candy, which was the second chocolate candy to ever be invented, predating milk chocolate by more the 20 years.

From there, the pairing of chocolate and hazelnuts only became more popular. What had begun as a cost saving measure turned into one of the most popular flavor combinations!

Variations on a Theme

Chocolate and hazelnuts need no improvement but there is always a twist to be added to any recipe. Just remember when you’re personalizing to be mindful of the nutritional values.

  • There is a lovely toasted flavor in the cookie base of these bars, if that’s a flavor you love, highlight it by toasting the hazelnuts and coconut for the topping.
  • Warm spices go nicely with nuts and chocolate, spice up your bars by adding 2 tsps cinnamon, 1 tsp orange zest and ¼ tsp each ginger and cloves.
  • Coffee is another flavor that pairs well with both chocolate and hazelnuts, try replacing the vanilla extract with a natural coffee extract.
