A classical gluttonous souvenir of Valle d'Aosta, tegole (literally meaning roofing-tiles) are round biscuits made with wheat flour, egg white, hazelnuts, sweet and bitter almonds. Their production in the Vallée confectioner's shops began about seventy years ago, probably according to a French recipe. It has been named after the "wavy" aspect of the biscuits which, after cooking in the oven, were dried on a rolling pin or on another cylindrical surface.
