Piedmont-style hazelnut cake, like most old-school Italian recipes, is based on cucina povera, Italy's waste-free "poor cooking" method. Due to the exorbitant expense of flour, the Piedmontese decided to forego it entirely and start making cakes out of one of the region's most famous delicacies: hazelnuts. Locals would hunt the woods in the autumn for any remaining hazelnuts from the enormous summer harvest, and thus the torta di nocciole was born.
Nowadays, there are dozens of variations of this beloved delicacy, many of which use flour. The Tonda Gentile Trilobata IGP from the Langhe, recognised by many as the best in the world, is Piedmont's most popular hazelnuts.
