The Christmas Dinner has everywhere some precise rules: in Umbria one of the most traditional dishes is something between a cake and a pasta dish.
Here is the recipe for the sweet macaroni with walnuts. 

Procedure

Prepare normal noodles, by mixing water and flour without eggs. 
As soon as the noodles have been drained, boil and dress them with sugar, cinnamon to taste, crashed walnuts kernels, the grated peel of a lemon and if desired cocoa to taste. 
There are no precise doses for the seasoning: it’s possible to adjust according to one’s own tastes, for example by exaggerating with one ingredient rather than with another one. 
At this point stir up and serve the cold dish!
