These sweet fried potato and flour doughnuts are somewhat like Spudnuts, which were a sensation in the US in the 1960s. In Calabria, they are often eaten at Christmastime. Also spelled cuddrurieddru.
The cuddrurieddra di Delia, made in Caltanissetta province in Sicily, have no spud, but are made with wheat, eggs, wine, sugar, orange peel and cinnamon and fried in olive oil the old fashioned way (with a special decorative dough 'crown'), in homage to the chatelaine of Delia, who was stuck in her castle during the War of the Sicilian Vespers; they are in the Ark of Taste.
Also see ciambella.
