Torta della nonna

Torta della nonna (lit. 'grandmother's cake') is a dessert typical of the Tuscany region of Italy.

Description
Torta della nonna originated in Arezzo, a comune (municipality) in Tuscany. It is a sweet pastry cake filled with vanilla-flavored custard and covered with pine nuts and confectioner's sugar. The creamy filling is flavored with fresh lemon zest. A flat pie pan or a taller springform pan can be used to bake the cake. The cake is usually served as the last course of the classic Italian Sunday meal.

History
The origin of this dessert has been debated. According to some, the true origin of this dessert can be traced to the Arezzo region, while others point to a more recent Florentine origin. Some sources say that the cake was born from a bet of Guido Samorini, a Florentine cook and restaurateur. According to the most common version, some customers, tired of the few desserts that the restaurant's kitchen offered, asked him for a surprise for the following week. Samorini presented them with the torta de la nonna "that was so pleasing for its taste and novelty". A passage from Pellegrino Artusi, however, casts doubt on the veracity of the story, and hints that the cake already existed many years earlier; the writers describes the cake saying: "...I found the dessert with pine nuts and custard a pleasant pie, a poor pastry...".

One variation of this dessert is torta del nonno, with includes cocoa, and almonds instead of pine nuts. Other variations include the addition of cherries inside the custard filling.
