This is a traditional dessert from the north of Spain, whose origin is uncertain but hotly contested, with autonomous regions such as Castile and León and the Basque Country claiming it as their own. Traditionally made at Easter, today it is made all year round and eaten all over Spain. Its basic ingredients are flour, sugar, eggs, milk, and cinnamon, which combine to make a soft dough that is left to stand and then fried in oil.
