Casadiella
The Casadiella is a typical dessert from Asturias. It consists of a pastry made of wheat flour, flavored with Anis del Mono ( Anisette) or wine, and filled with toasted hazelnuts or walnuts and sugar. They are mixed and they are fried together.
The final shape is a tube approximately ten centimeters long with ends that are closed with a fork.
